Spectrum™ Series Base Loaded Mobile AntennasManufactured by Motorola• Antenna Installation• Mounting Instructions• Cutting Charts • Replacement Parts• Connector InstructionsIntroductionThank you for selecting the Spectrum mobile antenna. The Spectrum antennas have been designed to withstand demanding and rugged environments. During the design phase, the antennas are put through extensive Accelerated Life Testing (ALT), which simulates years of in-field service. As a result, potential problems are designed out, helping to ensure that the antennas which you receive can give you years of dependable performance.Motorola Communications Part Division 1313 E. Algonquin Road Schaumburg, Illinois 60196 To order, Call Toll-Free: 1 - 800- 422 - 4210Before You Start Roof Mount Safety Precautions and Problem Prevention – for Motor Vehicle Use onlySafe Antenna InstallationRead all instructions carefully before starting the installation.Antenna contact with high voltage wires may result in death from electrocution.Since April 3, 1994, the warranty on Spectrum antennas have been changed to one year. Motorola manufactured Spectrum antennas are warranted to be free from defects in workmanship and materials for a period of (1) one year from the date of shipment.Be sure to mount the antenna on a horizontal surface to keep the antenna as vertical as possible, thus preventing the antenna from protuding beyond the vehicle and causing bodily injury and/or property damage.ImportantDANGERImportantC a u t i o n
2IntroductionEntering Garages Automatic Car Wash InstallationWhere to Mount the AntennaGeneralMotorola recommends that mobile antennas be located as follows:Select a location for the antenna as near the center of the roof as possible. Probe the headlining with your fingers to make sure that all points of obstruction are avoided.Remove the antenna from the vehicle when entering a garage to prevent damage to the vehicle and the antenna whip/ball from damaging overhead light fixtures and garage doors.Remove the entire antenna from the vehicle before entering the automatic car wash to prevent damage to the antenna and vehicle. The antenna mount contact must be wiped dry to prevent moisture from damaging the contact. Recommended Antenna LocationStandard Metal Passenger vehicles Recommended LocationStandard metal passenger vehicles Center roof or center trunk lidVans, pickups, and other light trucks (metal roofs)Center roofHeavy duty equipment with metal roofs (heavy duty trucks, semi-tractors, heavy refuse trucks, cement mixer trucks)Center cab roofSpecialty vehicles (such as T-roofs, sun roofs, or convertibles)Center trunk lid–recommended only for transmitter output of less than 7 W.Other vehicles Contact your Motorola Field Technical Representative.

Mobile Antenna Installation 3Mobile Antenna Installation Mobile Radio Operation and EME ExposureObserve the following caution and electromagnetic energy exposure (EME) statements when installing antennas: NOTE: For low power mobile radios (7 W or less), there are no antenna type or installation restrictions.To assure optimal radio performance and that human exposure to radio frequency electromagnetic energy is within the guidelines references in this document, transmit only when people outside the vehicle are at least the minimum distance away from a properly installed, external mounted antenna. Table 1 lists the minimum distance from several different ranges of rated radio power.Selecting an Antenna Site1. Install the vehicle antenna external to the vehicle and in accordance with the requirements of this documents.2. The best mounting location for the antenna is at the center of a large, flat, conductive surface. In almost all vehicles, mounting the antenna in the center of the roof will satisfy these requirements. A good alternative location is in the center of the trunk lid. If you use the trunk lid, ensure that the trunk lid is grounded by connecting groundling straps between the trunk lid and the vehicle chassis.3. Ensure the antenna cable can be easily routed to the radio. Ensure that the antenna cable is routed separately and not in parallel to any other vehicle wiring or mobile radio cable wiring.4. Check the antenna location for any electrical interference.NOTE: Any two metal pieces rubbing against each other, such as seat springs, shift levers, trunk and hood lids, exhaust pipes etc.) in close proximity to the antenna can cause severe receiver interference.5. If the vehicle is equipped with an electronic anti-lock braking system (ABS), and the antenna will be trunk mounted, then install the antenna on the side opposite to the braking modulator box. This minimizes radio interference to the modulator box from the radio.6. Make sure the mobile radio antenna is installed at least one foot (30.48 cm) away from any other antenna on the vehicle.Use caution when installing antennas with mobile radio equipment using transmitter powers in excess of 7 W.Table 1 Rated Power and DistanceRated Power of Vehicle-installed Mobile Two-Way Radios Minimum Distance from Transmitting Antenna7 to 15 Watts 1 foot (30.5 cm)16 to 50 Watts 2 feet (61 cm)More than 50 Watts 3 feet (91.5 cm)C a u t i o n

12 Mobile Antenna InstallationTuning the AntennaNOTE: Tune antenna in an open area at least 12 feet away from any metal objects.NOTE: Lengths shown on the cutting chart are approximate. Due to antenna variations and mounting location effects, we recommend cutting the antenna rod 1 1/2” longer than the chart and then cutting 1/2” off at a time until reflected power is minimized.NOTE: DUE TO ANTENNA INTERACTION WITH VEHICLE, SOME LOW BAND ANTENNA MOUNTING LOCATIONS WILL NEVER ACHIEVE 1.5:1 VSWR. In this case, trim the whip for minimum reflected power. A simple table for converting the radio of forward power and reflected power to VSWR is shown below in Tabl e 3 .1. Locate the transmitter frequency on the cutting chart. In the case of multiple transmitter frequencies, calculate the mid-frequency and locate on cutting chart. Read desired whip length from the chart. Cut the whip 1 1/2” longer than this length.NOTE: Trim the antenna rod (Low and High band) from the bottom only. On the UHF antenna whip, trim the whip from the bottom of the rod below the phasing coil.2. Use the set screw to secure the antenna whip in the whip adaptor assembly.3. Using the in-line wattmeter, measure forward and reflected power at the desired transmit frequency and calculate VSWR using Table 3.4. If VSWR is >1.5:1, then trim off 1/2” and repeat Step 3.5. Repeat steps 3 and 4 until minimum VSWR is obtained.496 – 512 5 dB Heavy 150 RAE-4016A RAE-4016ARA RAE-4016ATA RAE-4016AMAWith Low Loss Cable With Low Loss Cable406 – 420 5 dB Heavy 150 * * RAE-4012ARL RAE-4012ATL * *450 – 470 5 dB Heavy 150 * * RAE-4014ARL RAE-4014ATL * *470 – 496 5 dB Heavy 150 * * RAE-4015-ARL RAE-4015ATL * *496 – 512 5 dB Heavy 150 * * RAE-4016ARL RAE-4016ATL * *NOTE: All antenna mount kits include RG58A/U Cable and PL259 Connector, except cable option that is listed otherwise. ** For low and Mid Band Trunk lid mount kits, order antenna only and trunk lid mounting kit (01-80356A55) separately.PART NUMBER ANTENNA MOUNTS01-80352A03 Roof Mount Kit, RG58A/U Cable, PL259 connector01-80356A55 Trunk Lid Mount, RG58A/U cable, PL259 connector01-80356A47 Magnet Mount RG58A/U cable, PL259 connector01-80371A27 Magnet Mount RG58A/U Cable PL259 connector, low band onlyAdjusting the whip length while radio is keyed may cause burns from RF radiation.Table 2 Spectrum Antennas (Continued)Frequency MHz Gain Duty Max Power Watts Antenna Only Roof Mount Kit Trunk Lid Mount Kit Magnet Mount KitW A R N I N G

Insert the shorter part of the allen wrench into the screw and tighten the set screw at tight as yo can by hand. If a torque wrench is available, tighten set screw to a torque of 25 – 30 inch-lbs.A simple table for converting the ratio of forward power and reflected power to VSWR is given below:Example: If the forward power (Pfwd) is measured as 100 watts and the reflected power (Pref) is 3 watts, calculate Pfwd/Pref = 33.3.
