RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 1. Overview RF-11000E Operations Manual 2 Functional Description 1. The RF-11000E assembly is an RF through repeater designed for remote locations. Little alignment is required, and the use of highly reliable components and minimum active circuitry eliminates most subsequent maintenance. The repeater assembly consists of an equipment mounting panel, contained in an aluminum, weatherproof, enclosure. If desired, the complete assembly may be wall-mounted. In most applications however, the complete assembly is pipe-frame or tower-mounted. Front views of the repeater are shown in Figures 1 and 2. Bottom detail is shown in Figure 3. Typical Rack Mount Option is shown in Figure 4. 2. In addition to the RF-11000E repeater assembly, Peninsula Engineering Solutions offers accessory equipment consisting of static desiccator and pressure test assemblies, antennas and mounting hardware, waveguide, and complete site power supply systems. The recommended antennas are solid or high performance types chosen per application. Basic Repeater 3. The RF-11000E duplex repeater uses internally redundant amplifiers for transmission in each of two directions. Each amplifier is powered by two separate battery supplies for added reliability. Bandpass filters and circulators, which form a duplexer network, direct the received signals to the amplifiers, and then combine the amplifier outputs with the received signals to a common antenna port for transmission in each direction (see Figures 9 to 22). The repeater supports frequency division duplex, FDD, radio link systems where separate frequencies are used in each direction. 4. The received signal from "A" antenna, identified as frequency "f1", enters the repeater panel via the cabinet mounted WR90, cover flange and is then fed to a RX-TX branching circulator. Then from the channel branching circulator, the f1 signal is passed to the f1 receive bandpass filter. The bandpass filter passes the f1 signal to a terminated coaxial circulator and (optional) f1 receive pad and then to amplifier A1. The amplified signal passes through the (optional) f1 transmit pad. From the transmit pad the f1 signal then passes through a terminated coaxial circulator and the f1 transmit bandpass filter to the channel branching circulator and then to the RX-TX branching circulator. From there to cabinet mounted WR90, cover flange for connection to the "B" antenna. 5. In the other direction, the receive signal from "B" antenna, identified as frequency "f2", enters the repeater panel via the cabinet mounted CPR90G, flange and is then fed to a RX-TX branching circulator. Then from the channel branching circulator, the f2 signal is passed to the f2 receive bandpass filter. The bandpass filter passes the f2 signal to a terminated coaxial circulator and (optional) f2 receive pad and then to amplifier 2. The amplified signal passes to (optional) f2 transmit pad. From the transmit pad the f2 signal then passes through a terminated coaxial circulator and the f2 transmit bandpass filter to the transmit channel branching circulator and then to the RX-TX branching circulator and the cabinet mounted CPR90G, flange for connection to "A" antenna. 6. Receive pads RX f1 and RX f2 reduce the repeater receive signals to approximate the recommended input level. The transmit pads designated TX f1 and TX f2 reduce the output signal levels of the repeater for regulatory compliance and to prevent overloading of the terminal receiver on a short hop. Pads are mounted on input and output of amplifiers. Nominal input and output power level for various repeater channel configuration are listed at in Technical Summary following this section. 7. Delay Equalizers are added to correct for the slope and parabolic group delay introduced by the bandpass filters and branching networks. Equalized repeaters are recommended for high capacity systems, tandem repeater applications and multiple carrier 1+1, 2+0, 3+0, 4+0 configurations.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 1. Overview — 3 Amplifiers 8. In digital radio applications, in order to maintain linearity over the entire signaling envelope, the amplifiers operate at a reduced average power level to meet the output power level requirement as shown in Technical Summary. Each amplifier is mounted on the front of the panel to allow easy AGC/ALC and linear gain adjustments. It also provides easy amplifier replacement in the field. Necessary information for ordering spare or replacement amplifiers is provided later in Chapter 1, Ordering Information. Directional Couplers 9. Directional couplers, built into the amplifiers, provide signal monitor points, “RF MON”. These allow in-service measurement of transmit output power. The monitor points are calibrated for calculating the actual RF output power at the amplifier output and at the antenna port flange. When measuring transmit power, the power meter reading obtained, plus the loss (in dB) marked at the amplifier monitor point, minus the branching loss (in dB) marked on the panel, equals actual antenna port transmit output power. Example 1 Amplifier Output Example 2 Antenna Port Output Power Meter indication +5.0 dBm Power Meter indication +5.0 dBm Cal Loss at RF MON + 19.0 dB Cal Loss at RF MON + 19.0 dB Amplifier Output = +24.0 dBm Tx Branch Loss - 2.8 dB Antenna Port Output = +21.2 dBm AGC/ALC Adjustment 10. There is a field-adjustable potentiometer on each amplifier. The amplifier output power set level is adjusted by AGC/ALC potentiometer. This is a multi-turn potentiometer. Linear Gain Adjustment 11. On each amplifier, there is a second field-adjustable potentiometer for linear gain adjustment to limit its maximum gain. Gain adjustment is typically only used in cases where antenna isolation is inadequate to support the required C/E at maximum gain. In the majority of cases, the AGC/ALC automatic adjustments are all that is needed. Power Supply 12. The only active element in each frequency channel of the RF-11000E assembly is the amplifier which operates from a +8.5 VDC source. Two DC supplies of +24 VDC are brought into the repeater enclosure. They are converted to +8.5 VDC by two DC-DC converters and power the amplifiers in redundant-protecting mode. Current requirements, at +24 VDC, are 2.7 Amperes maximum per duplex system and 5.4 Amperes maximum per duplex, frequency diversity system. Solar Rated power consumption accounts for lower current demands under normal conditions. The repeater assembly may be powered from alternative energy source such as solar panels, wind turbines, thermal electric generators, fuel cells, primary cells only, or from an AC/DC supply with standby battery (shown in Figures 23 and 24). 13. Storage batteries and solar photovoltaic modules are selected on the basis of the insolation and temperature range at the site. The batteries are engineered to provide the required reserve capacity across the temperature range and during periods when the output from the PV array is low or not available. Controllers are used with the photovoltaic modules to efficiently charge the batteries without overcharging. Peninsula Engineering Solutions can determine the PV array and battery capacity. The location of the site should be specified when requesting assistance. 14. In areas where commercial power is available, an AC power supply can be provided. Although one AC power supply will provide ample current to power all amplifiers, dual AC power supplies are recommended for higher reliability. The dual AC power supply system also contains two
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 1. Overview RF-11000E Operations Manual 4 rectifier/chargers and two sets of standby battery to provide power during AC power failures. Each battery is float charged while the power supply is on and has 100 Amp-hours as standard capacity. Additional batteries can be purchased if needed. 15. In locations where commercial power is not available and solar panel charging is impractical, then alternative power sources such as thermal-electric generator, TEG, fuel cell, or motor generator are available. Power sources may be used in combination to create hybrid power solutions capable of operating in very demanding applications. Primary cell batteries capable of powering an RF-11000E repeater in excess of a year may be used. In such applications, the battery installation should be given an environmental shelter according to the manufactures’ recommendations. Contact Peninsula Engineering Solutions for assistance in designing the best power supply system. Alarms 16. The RF-11000E repeater can be provided with an optional alarm system (RMAS) to remotely monitor the repeater site. Conditions that are typically monitored are listed below: Standard Telemetry: a) A Battery Voltage b) B Battery Voltage c) Battery Temperature d) Auxiliary Voltage Standard Trip Points: c) A and B Battery Major Alarm d) East and West RF Output Low e) Amplifier Alarm f) Cabinet Door Open g) Feedline pressure low h) Uncommitted Points 17. The standard alarms are typically relayed back to the terminal site through the use of a low rate telemetry signal directly modulated on the microwave carrier in a non-interfering fashion. Alarms are visually displayed on the standard terminal receiver unit. Alarm contact closure outputs are available for input to standard microwave supervisory systems. 18. Alternative alarm equipment is available that transmits alarm data subset via UHF radio telemetry links operating in parallel to the microwave hop. This type of alarm equipment is used when access to the terminal radio AGC is not available or compatible. 19. Alarm closures can be converted to SNMP reporting over IP networks using Peninsula’s SNMP-SL10 unit.

This power “backoff” provides adequate linearity as required by the system performance objectives. The ALC adjustment on each amplifier is used to set the output power level. To calculate the repeater’s output power at the antenna port flange, take the amplifier power output without backoff, reduce that level by the backoff listed in this table, then subtract the transmit branch loss for the specific configuration from Tables 2 or 3. For Example: Level 2 Amplifier Power Output = +32 dBm without backoff reduction, Modulation is 256QAM, therefore backoff = 13.0 dB, RF-11000E-041 Tx Branch Loss = 2.8 dB,. Output power at antenna port flange = +32.0 – 13.0 – 2.8 = +16.2 dBm. 12 Modulations listed are the most popular types. List is not exclusive. If a modulation is not listed, contact the company for specific details.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 1. Overview RF-11000E Operations Manual 10 Ordering Information The RF-11000E RF Repeater Assembly is ordered by specifying the system model number RF-11000E-XXX (Table 4). Attenuators are provisioned by specifying their part numbers. Transmission engineering must be completed before ordering because the necessary attenuator values are determined from the path calculations. Part numbers are listed in Table 5. When doing the initial system layout of a radio link which includes an RF-11000E Microwave RF Repeater Assembly, several factors must be considered prior to ordering, to ensure correct antenna connections and proper installation. Consider the following topics before ordering the RF-11000E Microwave RF Repeater: Repeater Transmit and Receive Frequencies Repeater frequencies are coordinated with the adjacent terminal radios. See the block diagrams for more detail. Orders cannot be accepted without firm frequencies. Frequency assignment locations within the repeater can optimize the repeater antenna ports relative to the site antenna feedline routing. Peninsula Engineering can assist in determining the frequencies and assignments. Terminal Radio Modulation, Traffic Capacity, Bandwidth, and Repeater Transmit Power Level Repeater transmit power levels are set based on the modulation and traffic capacity of the adjacent terminal radios. Please include the modulation and traffic capacity details with the purchase order. Peninsula Engineering will determine the proper transmit power level. Modulations and traffic capacity beyond those listed in this manual may be possible to support, contact Peninsula Engineering Solutions for more details. Electric Power System The repeater site power system should be detailed during the system design phase. Peninsula Engineering Solutions can provide this design service and the power equipment. Power systems may include: Solar, Wind, AC, TEG, Motor Generator, Fuel Cell, or other power sources. All power systems include a battery plant and associated charge control equipment. Battery capacity must be adequate for the load, location, and power source. Antennas The types and sizes of antennas required to meet the system requirements. Transmission engineering can determine the antenna details. Transmission engineering and antennas are available from Peninsula Engineering Solutions. Feedlines Type and length required for antenna connections (including jumper assemblies); note that waveguide is available from Peninsula Engineering Solutions. Mounting Special requirements for the repeater and antennas specific to the intended tower or supporting structure. The repeater normally mounts outdoors in its all-weather enclosure. Peninsula Engineering Solutions can provide construction engineering support. Alarm System The Repeater Monitor and Alarm System equipment is optional. Please refer to Table 9 for ordering details or refer to the alarm equipment manuals. When ordering, specify a shipping destination and a billing address. Peninsula Engineering Solutions returns an order acknowledgment with the scheduled shipping date. Each shipment includes an equipment list showing the equipment ordered and shipped, including details about system and equipment options.

RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 2. Installation Instructions RF-11000E Operations Manual 40 Pre-Installation Site Review Each site should be thoroughly reviewed before any equipment is mounted. Site review should include, but not necessarily be limited to, the following factors: Weather Determine whether environmental conditions necessitate special shielding of the repeater or other equipment. Security Determine whether some type of barrier is needed to protect equipment and if a security light is required. Aviation Review tower heights and obstruction lighting requirements as specified by the national aviation authority, e.g. US-FAA, US Federal Aviation Authority or Transport Canada. Normally towers 200 Ft AGL and taller require obstruction lighting. Towers closer to airports have additional lighting and marking requirements. File NOTAMS as required during construction. Optional Site Equipment Determine whether additional site equipment, such as a convenience power outlet, pump, generator, or light is required, and, if so, where equipment is to be located and whether special enclosures for any equipment is required. Wiring and Wiring Access Determine any special wiring requirements. Cabinet Access Determine whether there is enough room for the repeater door to open, once mounted. The RF-11000E assembly can be mounted on a steel tower, on a steel pipe or square-rail frame, or on a wall. The length of all power leads should be limited and the wire size adequate to minimize the voltage drop. The repeater assembly, battery boxes, solar panels, and antennas should all be mounted before any wiring is done. Mounting-hole dimensions for the repeater enclosure are shown in Figure 26. Prior to cutting to length and connecting the waveguide feedlines, verify which repeater’s receive frequency associates with each antenna port and associated terminal radio site. The repeater receiving frequencies and transmitting frequencies are marked on the top of repeater, near waveguide antenna ports. Coordinate site names are marked in the same location, when known. The waveguide feedlines are terminated in CPR90G Flange. The repeater is not designed for pressurization. Use external pressure windows at the CPR90G Flanges if the feedlines are to be pressured or dehydrated. CAUTION: In an extremely hot and sunny environment, such as a desert, shading from direct sunlight may be necessary to prevent the repeater and associated equipment from overheating. Locating battery enclosures in the shade of the solar array is recommended.

RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 3. Mounting the Antennas — 43 Chapter 3. Mounting the Antennas Mount Antennas Mount all antennas, antenna feedlines, grounding, dehydration, and lightning protection. Test the completed antenna system installation prior to repeater equipment installation. Follow details of the site plan if available. Antenna Types Microwave RF repeaters can use any one of four typical parabolic antenna types:  Standard performance, single or dual polarized.  Improved performance, FCC Category A, single, or dual polarized (Deep Dish, PAR, PAD).  High Performance, single or dual polarized.  Ultra-High Performance, single or dual polarized. NOTE: Antenna type is normally determined by the system requirements, especially the repeater site antenna isolation objective for the radio system modulation. More complex modulations require greater Carrier to Echo, C/E and hence, greater isolation. Repeater system path calculations, path data sheet, are used to determine the antenna size and type. Antenna Mounting Location and Precaution Guidance Locate antennas such that RF energy exposure as described in US FCC OET Bulletin 65 is met. Normally antennas are located where the main beam is above the height of nearby persons and objects. Since the intent is to have clear line-of-sight path to the distant end, mounting locations meeting clear LOS will normally meet RF energy exposure limits. Appropriate warning signs must be properly placed and posted at the equipment site and access entries. See “Radio Frequency Radiation Hazard” section on page iii. Mount the antennas securely on adequate mounting structures. Mounting structures must meet strength, twist, and sway requirements for 11 GHz antenna systems. Provide means for alignment adjustments. Antenna Alignment Coarse Alignment To initially orient the antennas: 1. Align the “bore-sight” of the antenna to the calculated azimuth as shown in the site layout or path calculations. Be sure to account for geomagnetic declination when using a magnetic compass. Azimuths are normally shown as True North. Geomagnetic declination varies by site location and typically drifts every year as the location of the earth’s magnetic pole moves. 2. Adjust the elevation to match the calculated elevation angle. Fine Alignment using test radios 3. Peninsula Engineering recommends using test radios to do the alignment over the hop. This is much easier than attempting to use the limited repeater level indications or measurements. The test radios also provide a talk channel to allow the alignment teams to rapidly communicate with each other.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 3. Mounting the Antennas RF-11000E Operations Manual 44 4. Identify the polarization determined for the hop. Consult the antenna manufacturer’s documentation on identifying the vertical or horizontal antenna port on dual polarized antennas or how the feed assembly is installed and oriented in single (plane) polarized antennas. Failure to properly identify polarizations will result in antenna misalignment and violate the station license. 5. Attach the test radios to the proper antenna waveguide port at each end of the hop. 6. Consult the path calculations, PDS, for the net path loss calculated between the antennas. Correct for feedline losses when connected directly to the antenna waveguide ports. 7. Begin aligning the antennas. It should be possible to meet the calculated net path loss ± 1 dB. 8. Record the alignment and loss details. Provide the records to the end customer or controlling authority. Alternative Fine Alignment using repeater power measurements 9. This method requires the RF-11000E repeater to be installed, connected to the antenna feedlines, and powered up. See Chapter 4 for repeater installation details. 10. Before antenna orientation begins, the amplifiers must be operating in their full gain mode (out of AGC/ALC range). The setting of the AGC/ALC along with a high input level (greater than [desired output power level in dBm - max. linear gain in dB] ) may cause the normal action of the AGC/ALC circuit to mask changes in power due to azimuth and elevation sweeping of the antennas. The output power of an amplifier will increase in level as the input level is increased to the point where the AGC/ALC has been set (e.g. +18 dBm). Further increases in input level will be absorbed in the AGC/ALC circuit. Use the amplifier power monitor point as a signal strength indicator. The input level can be reduced temporarily by inserting a fixed or variable attenuator pad ahead of the amplifier. The attenuation required will range from 0 to 30 dB depending on desired power and input signal level. Remove the input semi-rigid coax cable and place the attenuator in series with the coax or use flexible coax as required for fit. Reduce the input level until the output power drops below the desired power level. If during antenna orientation, the power rises to the desired power level, reduce the input level again and then continue with antenna orientation. 11. Alternatively, the amplifier's maximum gain can be reduced such that the system is out of AGC/ALC for antenna alignment. Gain adjustment is provided by a potentiometer just below the AGC/ALC adjustment. Be sure to return the potentiometers to their normal positions after antennas are aligned. (Usually at the maximum linear position.) 12. Connect the power meter or spectrum analyzer to the f1 amplifier, A1, RF MON port. With a signal transmitted from the A terminal, position the antenna A for a maximum power reading on the meter or analyzer. After antenna A is aligned, remove any temporarily installed input attenuators. Re-set the power level with the AGC/ALC adjustment if needed. The AGC/ALC adjustment is located near the output end of each amplifier, see Figures 7 and 8. Use a screw driver or tuning tool to adjust the AGC/ALC potentiometer CW to reduce the power setting or CCW to increase the AGC/ALC set point. Log the power reading to fulfill FCC requirements. Remove the meter from the f1 Amplifier RF MON to the f2 Amplifier RF MON. 13. With a signal transmitted from the B terminal, position the antenna B for a maximum power reading on the meter or analyzer. After antenna B is aligned, remove any temporarily installed input attenuators. Set the power level with the AGC/ALC adjustment if needed. Log the power reading to fulfill FCC requirements. Measure and log the power at any additional amplifier (RF MON) directional couplers so equipped (f3, f4...). Remove the meter. 14. After the antenna orientation has been completed at both terminals and the repeater, AGC/RSL readings should be taken at the end terminals and logged for reference. Provide the records to the end customer or controlling authority.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 3. Mounting the Antennas — 45 Antenna Feedlines The RF-11000E repeater uses waveguide feedlines. For the 10.7 ~ 11.7 GHz band, typical feedlines are elliptical waveguide such as EWP90 and EP105. The RF-11000E has CPR90 Flanges at the top antenna ports. The equipment end of the waveguide feedline must have a matching CPR90 contact flange installed. The antenna end of the waveguide feedline must have a connector flange that matches the installed antenna’s flange. Typical antenna flanges in this band are CPR90G and PDR100. Waveguide feedlines require dehydration equipment to maintain a dry atmosphere within the waveguide to prevent moisture accumulation which leads to corrosion and higher transmission losses. RF repeater applications typically have shorter waveguide runs and thus, a smaller volume of air within the waveguide. Static desiccators are ideal in this situation. A static desiccator will passively dry air passed through its silica gel as daily temperature and pressure changes gently move the air. These units do not require any power to operate and provide 1 to 2 years field lifetime before requiring replacement or service. Peninsula Engineering recommends mounting static desiccators inside the repeater enclosure to protect against aging from direct sunlight. See manufacturer’s specifications and recommendations when considering static desiccators. Dry Nitrogen is another method to keep waveguides dry without using power. Nitrogen supplied in high pressure bottles is reduced in pressure with a regulator and then passed to a gas pressurization manifold with distribution to the feedlines. Nitrogen replaces the air within the waveguide (purged at installation) and the positive pressure helps force moisture away from entering the waveguide. To warn of an empty gas bottle, the optional RMAS alarm equipment can be optionally provisioned with a low pressure switch that can be added to the pressurization manifold. When gas pressure drops below 1 psi, a warning alarm is issued. RF-11000E repeater configurations require one feedline per equipment antenna port, typically: ⇒ One for the primary West antenna ⇒ One for the primary East antenna ⇒ One for the diversity West antenna, if applicable ⇒ One for the diversity East antenna, if applicable ⇒ One per direction and polarization in Y-Junction applications The allowable transmission loss for antenna feedlines is specified in the site plan or path calculation, path data sheet documentation for the project. Do not install feedlines different than as specified. Feedline Installation To install waveguide feedlines: 1. Install the top connector (goes to the antenna). Use a flaring tool for best attachment and impedance, Z0, match. 2. Raise the cable up the tower to the antenna. Use a hoisting grip. 3. Position the waveguide and secure the top section. Carefully bend the elliptical waveguide to align with the antenna flange. Be mindful of the bend and twist specified limits of the waveguide. If necessary, use rigid twist and bend sections to aid in alignment. 4. Connect the waveguide to the antenna. 5. Securely install the feedline so that it reaches to the installation site of the RF-11000E, with enough room to connect to the repeater. 6. Secure the cable to the tower or structure about every 3 feet or 0.9 meters. 7. Carefully measure and cut to length the waveguide. 8. Terminate the waveguide with a CPR90 flange connector.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 3. Mounting the Antennas RF-11000E Operations Manual 46 9. Position the waveguide and secure the bottom section. Carefully bend the elliptical waveguide to align with the repeater equipment top flange. Be mindful of the bend and twist limits of the waveguide. If necessary, use rigid twist and bend sections to aid in alignment. 10. Flexible twist-flex waveguide jumper may be used at either end if needed. These jumpers have higher loss and shorter life than rigid twist and bend sections. 11. Trial fit the bottom connector to the repeater equipment top antenna port flange or intended flange location. Do not permanently install until the feedlines are sweep tested. 12. Install waveguide grounding kits. Normally the waveguide is grounded at the top and bottom and at the shelter entrance. Follow grounding practices prescribed by the controlling authority. 13. Pressure windows are recommended at the repeater equipment top antenna ports. 14. Install dehydration equipment. Lightning Protection Peninsula Engineering Solutions strongly recommends installing protection on the tower, structure and on all feedlines to the repeater. A direct lightning strike can damage any electronic equipment. Damage resulting from a lightning strike is not covered under the equipment warranty, whether or not lightning protection is used. However, using lightning protection can minimize the risk of damaging a repeater, and of losing equipment operation during thunderstorms. Elliptical waveguides are protected by installing grounding kits, typically at the top, bottom and at shelter entrance. Lightning rods mounted adequately above the highest antenna or power equipment provide a diversion path for lightning strikes. Multiple lightning rods may be required. Towers, shelters and all equipment must be bonded and grounded to minimize any potential differences that can occur due to a lightning strike. Follow grounding practices prescribed by the controlling authority. Sweeping the Antenna Feedlines Sweep testing of the installed feedlines and antennas is recommended. Sweep testing is the same as performed at a terminal radio site. Measurement of impedance match and insertion loss over the operating frequencies insures that the antenna system is installed properly and is ready to perform. Most microwave operating companies have developed their own performance standards for antenna systems. Use such standards if available. If company standards are not available, consider the following:  Sweep frequency range: 10,700 ~ 11,700 MHz or across all assigned channel bandwidth.  Impedance Match: 20 ~ 26 dB Return Loss or 1.22:1 ~ 1.11:1 VSWR across the channel bandwidth. If tunable connectors are provisioned, adjust the tuning screws to optimize the match.  Insertion Loss: Per calculated. Typical waveguide loss13 is 3.0 dB/100 Ft or 10.0 dB/100 m.  Distance to Fault, DTF: Measure Return Loss of the antenna system components and isolate troubles. Use DTF function of Anritsu Site Master™ test equipment. If the impedance match or insertion loss is not met, troubleshoot the feedlines and antennas for the source of the problem. Use the “Distance to Fault” function to assist in localizing the trouble. Correct as required before proceeding. 13 EWP90, EP105. Consult manufacturer’s specifications for loss at the intended frequencies.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 3. Mounting the Antennas — 47 Measuring Antenna Isolation – Decoupling System path calculations by Peninsula Engineering will determine the recommended antenna size and type plus the feed-horn to feed-horn separation and polarization loss. Our experience has been that if the recommendations are followed, antenna isolation will be met with some margin and direct measurement of antenna isolation is not required. Should there be reason to determine the antenna isolation, proceed with this section. Measure the actual isolation between the antennas, to ensure that the antennas are sufficiently isolated from each other and that the system Carrier-to-Echo Ratio, C/E, objective is met. CAUTION: This is an important consideration in all on-frequency repeater installations. If the isolation is not sufficient, the repeater might oscillate in the extreme, or the repeater system might have inadequate carrier-to-echo ratio, C/E, margin, which can lead to bit errors in digital radio systems. In some cases, it may be necessary to reduce the maximum repeater gain by adjusting the amplifier’s GAIN setting potentiometer and thus obtaining the required C/E. Normally isolation is met and amplifier GAIN setting allows for maximum ALC managed gain. C/E = [Isolation, dB] – [Repeater Operating or Maximum Gain, dB] Example 1: Isolation = 110 dB, Operating Gain (ALC reduced) = 45 dB C/E = 110 – 45 = 65 dB Example 2: Isolation = 110 dB, Maximum Gain (full gain) = 60 dB C/E = 110 – 60 = 50 dB Table 10 lists the C/E and isolation objectives for various radio modulation types. Isolation is controlled by the antenna Front-to-Back, F/B, ratio, sidelobe suppression, separation distance between feed-horns, angle between the antenna centerlines, polarization, and feedline losses. Measuring antenna isolation requires a signal generator and a spectrum analyzer. The generator transmits a signal from one antenna, and the spectrum analyzer measures the same signal as the second antenna receives it. Figure 27 shows the equipment set-up. Losses between 80 and 120 dB are measured. Be sure the test equipment is capable of adequately measuring such high loss values.

The time offset or echo delay is typically close to 200 nanoseconds with 50 feet, 15 meters, of combined feedlines. In medium to high capacity digital radio systems, this time offset results in intersymbol interference. Adaptive equalizers can reduce the effects of the echo signal. The objective C/E values listed assume minimal correction from adaptive equalizers or forward error correction. As a result, performance may be better than predicted depending on the microwave radio equipment capabilities. 14 For < -1 dB system gain at 10-6 BER or BER < 10-12 at normal RSL. 15 Isolation objective assumes a maximum repeater net gain of 60 dB. Isolation required for a specific C/E decreases dB-for-dB as the maximum gain decreases.

Mounting the Antennas — 49 Figure 27 Antenna Isolation Measurement - Equipment Configuration NOTE: In all cases, measure antenna isolation with all feedlines, jumpers, cables, and connectors in place. Record all measurements for future reference. The equation for antenna isolation measurement is: ISO = PGEN – (LC-GEN + LC-SA) - PSA Where: ISO = Isolation in dB between the antennas. PGEN = Output level of the signal generator (dBm). LC-GEN = Loss of the signal generator cable, CASG (dB). LC-SA = Loss of the spectrum analyzer cable, CASA (dB). PSA = Power indicated on the spectrum analyzer (dBm). For example: PGEN = 10 dBm LC-GEN = 1.0 dB LC-SA = 1.0 dB PSA = -92 dBm ISO = 10 dBm – (1 dB + 1 dB) – (-92 dBm) = 100 dB

Mounting the RF-11000E RF-11000E Operations Manual 54 Earth, Ground, and Lightning Protection When grounding the RF-11000E and associated equipment, follow the general guidelines in the Peninsula Engineering Solutions application note, Installation Standards for Grounding Requirements. Installing the input power to the repeater includes installing the standard electrical service grounds. However, you must also make sure that the repeater enclosure is properly grounded to an earth ground. The repeater enclosure includes an external grounding lug on the bottom surface as shown in the following figure. Figure 32 Location of Ground Lug on Repeater Enclosure 1. Connect the screw-compression ground lug to a suitable earth ground—copper ground rod, copper pipe, ground ring, grounded steel building frame or similar ground point—using 2 to 4 mm, No. 12 to 6 AWG copper wire. 2. Carefully dress the wire along cabinet, and the mounting surface, to the Repeater Grounding System or the Ground Rod. Recommend using CADWELD® to attach the ground wire to the rod or ground point. NOTE: When dressing the grounding wire, and forming it around corners; avoid making sharp bends in the wire. Use a generous radius for each wire bend. Sharp bends will cause arc points for lightning surges and strikes. Ground Lug

RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 5. Repeater Tests — 57 Chapter 5. Repeater Tests Overview This chapter describes how to test the RF-11000E repeater, to set levels and to verify that it is operating properly. Test Equipment Required Table 8, in Chapter 2, lists test equipment and tools required for testing the RF-11000E repeater. Equivalent equipment may be substituted. Applying Power to the Repeater 1. Confirm the repeater is connected to the antenna feedlines, is grounded and that the power system has been installed and tested. Confirm that all fuses are removed, amplifiers are unplugged, and RMAS-120 is switched off. 2. Apply primary DC power to Battery A and B terminal blocks TB1 and TB2 on the repeater main panel. 3. Measure the DC voltage at TB1 and TB2. Make sure that the voltage is within the operating parameters of the repeater: • +24 Volts DC: +19 ~ +30 VDC. Nominal lead acid battery voltage is +25.2 VDC when fully charged and +27.0 VDC when being charged. Correct as necessary 4. If the optional RMAS-120 alarm equipment is provisioned and installed, switch ON the alarm transmitter. Press the yellow LED switch on the lower left to observe all LEDs illuminate and then report current alarm conditions. To make testing easier, set the LED Switch jumper to DIS. This will allow the LEDs to report without pressing the LED switch. • When finished testing, the LED Switch jumper is returned to the ENB position to conserve power by only displaying alarm LEDs when the button is pressed. 5. If the DC power is correct, all the LEDs will light briefly, then these alarm conditions should be present: Alarm Condition Battery A Low Clear Battery B Low Clear Door Alarm when door is open W/G Either PWR F1 ~ F8 Clear (amplifiers unplugged) AMP 1 ~ 8 Clear (amplifiers unplugged) UNCOM SUM (UC1 ~ 7) Either, clear if not used
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 5. Repeater Tests RF-11000E Operations Manual 58 6. Insert all fuses. Plug in all amplifier power plugs. Alarm conditions may change. Alarm Condition Battery A Low Clear Battery B Low Clear Door Alarm when door is open W/G Either PWR F1 Either PWR F2 Either PWR F3 Either if equipped, otherwise Clear PWR F4 Either if equipped, otherwise Clear PWR F5 ~ F8 Clear AMP 1 ~ 8 Clear. Any AMP alarm is a concern and potential amplifier failure. UNCOM SUM (UC1 ~ 7) Either, Clear if not used. 7. Once the Battery A and B alarms clear or TB1 and TB2 are between +19 and +30 VDC and when measured voltage at TB3 shows +8.5 ~ +9 VDC, then the repeater is powered and ready for testing. 8. Current Test: Measure the Battery A and B current flowing into TB1 and TB2. Repeaters with equal numbers of amplifiers will have the two battery inputs close to equal and approximately half of the total current listed in Table 1. If either battery input has a low or zero current, check the battery source and distribution system. Record currents for reference. 9. The repeater can operate on a single A or B battery input when needed. Each amplifier can draw power from both DC/DC converters and thus either battery input. When one battery source is removed or failed, all the current per Table 1 will flow into the remaining working battery feed. Transmit Power Adjustment At this point, the antennas should be mounted, feeders swept, antennas aligned and isolation confirmed. The repeater’s power amplifiers have been factory set to the specified output power levels per the system modulation, when known. Fine adjustments are recommended for best performance. Greater than recommended power levels can result in amplitude distortion, radio, and line errors (BER). Less than recommended power levels may have been selected by transmission engineering (e.g. short hops). Refer to system path calculations and path data sheets for details. To measure and adjust output power: 1. Calibrate the RF Power Meter for 11 GHz operating frequencies. 2. The far end transmitter operating on repeater frequency F1 must be transmitting at this time. 3. Connect the power meter to the RF MON test port on the side of Amplifier A1 (F1 PA). This is an SMA-female connector. A right-angle adapter with a between series (e.g. SMA to N) adapter (if needed) to fit the power meter sensor are needed to access the test port. 4. Measure and record the power meter reading. Typically, this reading will be between -15 and +15 dBm at RF MON. 5. Add the Cal Loss marked near the RF MON (see Figure 35) to the power meter reading, the result is the Power Amplifier Output Power.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 5. Repeater Tests — 59 6. Compare the Power Amplifier Output Power reading to Table 4, using the listing for the radio modulation type used. 7. Adjust the AGC/ALC potentiometer as required to set the power amplifier output level equal to the listing in Table 3. • Note: Lower levels may have been selected by transmission engineering, please refer to system path calculations and path data sheets for details. 8. Once the power levels have been set, confirm the RMAS Alarm Transmitter PWR alarm is clear for each frequency equipped. If the PWR alarm remains active and the transmit power is correct, then the RMAS Alarm Transmitter alarm point must be adjusted. Please refer to the alarm equipment documentation for adjustment details. The alarm point is normally 5 dB below normal operating power level. Alarm Condition Alarm Point Battery A Low Clear < 23 VDC Battery B Low Clear < 23 VDC Door Alarm Door Open W/G Either Pressurization Low, < 1 PSI PWR F1 Clear 5 dB below normal operating power PWR F2 Clear “ ” PWR F3 Clear “ ” PWR F4 Clear “ ” PWR F5 ~ F8 Clear “ ” when equipped AMP 1 ~ 8 Clear Current out of range, high or low UNCOM SUM (UC1 ~ 7) Either, Clear if not used. Closure on UC# position 9. To determine the Antenna Port Output Power Level, subtract the TX Branch Loss from the Power Amplifier Output Level. The TX Branch Loss is marked on the repeater panel near the PA. Include any transmit attenuator pad loss if equipped. Figure 35 Power Amplifier RF MON and TX Branch Loss
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 5. Repeater Tests RF-11000E Operations Manual 60 Receive and Transmit Attenuator Pads Receive, RX, pads attenuate input signals that are greater than can be compensated by the repeater amplifier’s AGC/ALC circuits. Receive pads are installed on the amplifier input (RF IN) jack. Transmit, TX, pads attenuate output signals. Transmit signals can also be reduced by adjusting the AGC/ALC potentiometer. In cases of very short hops, more power reduction may be needed. In these cases a TX Pad is normally installed. Transmit pads are installed on the amplifier output (RF OUT) jack. Pad Installation: 1. If required in the field, the RX/TX attenuator pads should be installed at the RF input or output of the amplifiers. 2. To install the pad, turn OFF the DC power supply first. 3. Disconnect the input or output semi-rigid coax cable from the amplifier. 4. Connect the SMA male end of the pad to the amplifier’s SMA female input or output; and then connect input or output cable to the female end of the pad. 5. Check all coaxial connections for tightness (8 in-lbs). 6. Turn ON the DC power supply. 7. Set output power level by adjusting AGC/ALC. Radio Link Tests Once the repeater levels have been set and confirmed and antenna alignment is accepted, then, confirm microwave signals are received at each terminal radio. Observe and record the receiver AGC or RSL indications for reference. End to end link tests can now be run. These tests may typically include un-faded BER, radio errors, system thermal and intermodulation noise. Refer to the radio terminal equipment documentation and system engineering requirements for the link test plan. Completion When setup and tests are complete, set the RMAS Transmit Alarm LED SWITCH jumper to the ENB position to conserve power by only displaying alarm LEDs when the yellow test button is pressed. Refer to the RMAS-120 manual for alarm system tests.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 6. Maintenance and Troubleshooting — 61 Chapter 6. Maintenance and Troubleshooting The RF-11000E active components are the linear power amplifiers, the DC/DC converters, and the optional RMAS alarm equipment if equipped. RF repeaters provide long field operating life, often 15 to 20 years. Technologies and traffic needs often drive upgrades or replacement rather than old age. Routine maintenance checks of the repeater and its supporting equipment will ensure reliable operation and early detection of problems. Routine Maintenance Peninsula Engineering Solutions recommends an annual maintenance schedule for the repeater. The following is a procedure for routine maintenance: 1. Observe the general condition of the installation site and correct any problems. 2. Verify that the repeater and all associated hardware, including antennas, is securely mounted and properly in place. 3. Check input electrical wiring and power system for damage and ensure that connections are tight. Replace any wiring that is suspect. 4. Check any battery terminals for corrosion; clean terminals, if necessary. 5. Check the battery storage capacity condition. Battery impedance testers are recommended. Battery life expectancy is typically 5 to 10 years in an outdoor environment. Replace any weak batteries or cells. 6. Clean solar panels and remove obstructions, if applicable. A mild detergent and water are recommended. Clean solar panels when they are cool, avoid putting cold water on hot panels, this may cause damage. Dirt, thick dust, and bird droppings can reduce the output by 30%. Shadows from antennas, lightning rods, or trees reduce PV output. Life expectancy of PV arrays is 25 years or more. Performance typically declines after 20 years operation. CAUTION: Follow manufacturer’s instructions when cleaning solar panels. Abrasive or acetone-based solutions can cause damage. 7. Look for lightning strike damage. Solar panels with “holes” punched in the backing material indicate a lightning strike. Damaged solar panels or equipment should be replaced. 8. Check antennas and feedlines for damage and ensure that connections are tight. 9. If the feedlines are pressurized, check that pressure is holding correctly, dehydrators are working or Nitrogen gas tanks are full. 10. If static desiccators are used to dry the feedlines, check the desiccant color. Blue16 or Orange is normal; Pink or Green indicates the desiccant is full of water and needs changing. Static desiccators should be changed typically, about every 1 to 2 years. 11. If feedline pressure is zero or desiccants are very pink, it’s best to check the feedlines for water. Drain and dry as required. Inspect for corrosion, correct or replace as required. 12. Check the RMAS alarm transmitter for indications of alarms or trouble. 13. Measure the RF power output level at the RF MON ports. Compare to records. 14. Measure the DC battery load current. Compare to records. 16 Color depends on desiccant material used. Check manufacturer’s specifications. Orange-to-Green desiccant is EU/CE Compliant.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr — Chapter 5. Repeater Tests RF-11000E Operations Manual 62 Administrative Requirements The US-FCC or other local Tele-communications Administrations may require measurement of the output power of the repeater at installation or when any changes are made which cause the output power to change. Using the power meter, measure, and log the output power as directed in Chapter 5. Troubleshooting Soft failure of one amplifier will be indicated by a drop of approximately 6 dB in the received signal level at the terminal in the direction of transmission, which will be indicated on the AGC, RSL meter on the terminal equipment. Amplifier AGC/ALC may correct for this drop. The failure of one amplifier will most likely be caused by a failure of DC power to the amplifier. Using the DVM, check for presence of DC voltage at the amplifier power feed through connections. Another way to check is insert DVM probes to pins #1 and #2 (Primary DC), then #1 and #3 (Secondary DC) from the back side of amplifier wire harness as shown in Figures 7 and 8. Pin #1 is Ground. Amplifier DC voltage should be +8.4 ~ +9.0 V. If the received signal at the terminals is low but does not indicate a complete failure on one amplifier, the most likely cause is low voltage from the batteries. Low voltage is an indication of a possible DC-DC converter failure, battery failure, or a failure of the charging system. In the case of the primary cell batteries, the batteries are probably reaching the limit of their life. Check the batteries and all power lead connections. If solar panels are used, be sure they are not obstructed from sunlight and that the surfaces are clean. If an AC power supply is used, low voltage is probably the result of a power failure, the duration of which exceeded the reserve power limits of the standby battery. Check the standby battery in accordance with the instructions given by the manufacturer of the power supply. NOTE: Contact the Customer Service Department of Peninsula Engineering Solutions whenever problems with the unit cannot be resolved. Table 11 System Troubleshooting Problem Cause Solution Overheating Inefficient Cooling⇒ • Clear any airflow obstructions. • Shade the unit if it is in an extremely hot environment. Low Voltage or No Voltage (Low Battery Alarm) Improper Solar Charging⇒ • Clean solar panels or remove obstructions. • Do not use an acetone-based solution for cleaning.

RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 6. Maintenance and Troubleshooting — 63 Problem Cause Solution Repeater fails overnight and then restarts the next day (Solar Powered) Improper PV Charging⇒ • Check the PV array for damage, obstructions, or dirt. PV Array wired to wrong voltage⇒ • Check the PV open circuit voltage, Voc. • Typically the Voc will be 1.5 to 2 x the battery nominal voltage. If Voc is more than 3 x the battery nominal voltage and PWM17 type PV controllers are used, the array is mis-wired. • Voc may be greater only if MPPT18 type PV controllers are used. Alarm Conditions⇒ • Check for alarm conditions and resolve, if necessary. Battery capacity low⇒ • Batteries may be worn out or undersized, replace and correct as necessary. Prolonged storms⇒ • Storms or series of storms can reduce battery recharging for days. Batteries may be fully discharged causing the system to fail. Re-evaluate the power source capacity, increase the PV array or add secondary power source, increase the battery plant Ah capacity. Low RF Output - or – No RF Output Amplifier power not set⇒ • Set the amplifier output power level per radio modulation. Antennas Oriented or Polarized Incorrectly⇒ • Check antenna orientation and re-align, if necessary. • Confirm the correct polarizations are used. Alarm Conditions⇒ • Check for alarm conditions and resolve, if necessary. Amplifier Failure⇒ • Replace the linear amplifier. Terminal radio OFF⇒ • Confirm the terminal radio is transmitting. Improper gain setting⇒ • Check gains and re-set, if necessary. RF Output cannot be set Input level LOW⇒ • Low input level can be normal, refer to path calculations for expected levels. • Confirm the terminal radio is transmitting. • Confirm frequencies and polarizations match. Amplifier low gain failure⇒ • Damage to the amplifier can cause low gain which in turn will reduce the available RF output power. • Replace the linear amplifier. No Receive Signals at both ends Problem Common to both directions.⇒ • Check items in common with both directions of transmission. Antennas, Feedlines, Site Power or Multiple Failures. • Check Feedline connections; confirm correct antenna port to antenna direction. Feedline reversal will result in no signals at the ends and input to the repeater amplifiers due to the bandpass channel filters. Antennas Oriented or Polarized Incorrectly⇒ • Check antenna orientation and re-align, if necessary. • Confirm the correct polarizations are used. 17 PWM: Pulse Width Modulator. PV Controller type that uses a rapid switch to reduce the average charging current when batteries are fully charged. PV Array Voc should be 1.25 to 2.0 x the nominal battery voltage. Higher Voc can indicate the array is mis-wired (series instead of parallel) resulting in less charging current and power. 18 MPPT: Maximum Power Point Tracking. PV controller type includes a DC/DC converter to “step down” higher voltage PV arrays. Maximum Voc is limited to the maximum rating of the MPPT controller, typically 150 to 200 VDC.

Charge and Load should be separate. • Typically occurs on sunny afternoons. Amplifier Replacement Repeater amplifiers are wideband and cover the full frequency range specified for the repeater, bandpass filters control the channel assignment. Amplifiers with the same part number can be used as replacements. When an amplifier must be replaced, do the following: a) Unplug amplifier's power connector. b) Disconnect input and output SMA cables. c) Disconnect the BNC cable from DC monitor point. d) Remove mounting hardware (11 screws). Hardware may be Pan Head Philips screws or Socket Head Cap screws. The socket head cap screw hardware takes a 3/32 or 7/64-inch Hex Allen Wrench. e) Remove amplifier.
RRFF--1111000000EE MMiiccrroowwaavvee RRFF RReeppeeaatteerr RF-11000E Operations Manual Chapter 6. Maintenance and Troubleshooting — 65 To install the replacement amplifier: a) Apply heat sink compound to the mounting surface of the amplifier. Use a very thin layer. b) Mount the amplifier on the panel, secure with mounting hardware. c) Connect the BNC cable to DC monitor point. d) Connect input and output SMA cables. Use care to align the SMA connector. Misaligned connectors can destroy the center pins. e) Check all coax connections for tightness (8-inch/lbs) f) Plug-in the amplifier's power connector. g) Verify operation by measuring power at SMA power monitor, PWR MON. h) Set output power by adjusting AGC/ALC per Chapter 5. i) Confirm the RMAS alarm transmitter PWR alarm clears. Adjust the alarm as required. ii) Amplifier’s RF Detector DC sensitively and output can vary, thus requiring adjustment. Keeping Spares Because repeaters are often used to provide critical coverage, customers are advised to follow a sparing policy. While most telecommunications carriers or system operators have internal policies relative to equipment sparing, in the event that one does not exist, Peninsula Engineering Solutions recommends maintaining a minimum of one (1) spare unit for every increment of 10 units or fraction thereof. This assumes that all spares are immediately available to the technician in need for installation. When travel time to a site is long or access is difficult (helicopter, hike or horse), then, more spares located close to or at the repeater site are recommended. Frequently, organizations will store an amplifier inside an RF repeater, thus, placing the spare exactly where needed. Amplifiers stored in sealed, anti-static packaging is recommended for on-site spare inventory. Each organization should develop a company-specific, equipment-specific policy that meets their needs, taking into account geographic considerations, and the quantity of repeaters used in the network.
