21. Scope of ManualThis document covers the procedures for installing the Satellite Series Fixed Site Antenna, and theit’s optional cable system, and is to be used with the Satellite Series 9520 Mobile or Satellite Series9570 Portable Dock. This manual is intended for use by experienced technicians familiar withinstallation of antennas for similar types of equipment.2. How to use this ManualThis manual covers the procedures for installing and mounting the Fixed Site Antenna, for routingand connecting associated cabling, and for dealing with lightning and surge suppression. Beforeinstalling the 9520 Mobile Phone or 9570 Portable Dock or it’s antenna, read the information relatedto installation planning and lightning/surge protection covered further in this manual.3. General Safety PrecautionsDuring normal use, the Satellite Series portable telephone will emit radio energy substantially belowthe level where any kind of harm is reported. However, to ensure personal safety and to avoidequipment damage, please observe the following simple rules:• To assure that radio frequency (RF) energy exposure to bystanders near the antenna is lowerthan that recommended by the adopted standard, operate the 9520 Mobile Phone or 9570Portable Dock only when bystanders are at least 60 cm (24 inches) away from a properlyinstalled externally mounted antenna.• For proper Iridium system operation, do not operate 9520 Mobile Phone or 9570 Portable Dockwhen someone is within 20 cm (8 inches) of the antenna.• DO NOT operate the telephone unless all RF connectors are secure and any open connectors areproperly terminated.• DO NOT operate the 9520 Mobile Phone or 9570 Portable Dock near electrical blasting caps orin an explosive atmosphere.• All equipment should be serviced and installed only by a qualified technician.• Refer to the appropriate section of the product service manual for additional pertinent safetyinformation.4. Installation Safety WarningWhen choosing a location for the 9520 Mobile Phone or 9570 Portable Dock and the antenna, besure to consider the operator and bystander’s safety. Be sure to mount the 9520 Mobile Phone or9570 Portable Dock and the antenna such that the General Safety Precautions outlined in Section 3above are not violated during normal use by operators and bystanders. Be sure to route the cablebetween the 9520 Mobile Phone or 9570 Portable Dock and the antenna in such a way that it doesnot pose an obstruction to the users. Take steps to insure that the antenna is mounted in such a waythat it will not become detached from it’s supporting structure under normal external forces.
35. Antenna Installation PlanningThe Satellite Series Fixed Site Antenna system consists of a fixed mount antenna and a coaxial cablethat connects the 9520 Mobile Phone or 9570 Portable Dock to the antenna . It is suitable for bothmarine and terrestrial applications, and is designed to meet Iridium system performance requirementswhen installed per this manual. A typical terrestrial application is depicted in the Diagram “A”below.The Satellite Series Fixed Site Antenna is a helical antenna contained inside a weatherproof housing,and is intended to be mast mounted without a ground plane of any type. It’s location should bereasonably clear of nearby metal obstructions and such that a distance of at least 20 cm ismaintained between the antenna and the user. For proper performance in the Iridium system, theantenna must have a clear view of the sky from the horizon on up and must be mounted vertically.While horizontal obstructions may not be totally avoidable, they should be minimized, for they mayresult in a spot(s) of poor system coverage. This will decrease or possibly eliminate the ability tooperate the Iridium Satellite Series portable phone unit at times which are not predictable by theuser.The connection between the Satellite Series Fixed Site Antenna and the 9520 Mobile Phone or 9570Portable Dock is accomplished using specialized coaxial cable system. This cable system is offeredas an option to the Fixed Site Antenna. Alternatively, the user can choose cables from other suitablesources, following the guidelines outlined further in this manual.To minimize the loss of radio signal from the antenna to the 9520 Mobile Phone or 9570 PortableDock, the coaxial cable system between those two components should be as low loss as possible.Listed below in Table One are a selection of coaxial cables available from Times MicrowaveFixed Site Antenna8.5 meter Main Coaxial CableHigh Frequency Surge SuppressorAntenna Support StructureSatellite Series Portable Phone or Portable Dock0.5 meter "Jumper" Coaxial Cable1.5 meter "Jumper" Coaxial CableDiagram A--Typical Fixed Antenna and Cable Installation( Dwelling)

The other cables listed are also availablefrom Times Microwave, and are provided for reference in those applications where longer cableruns are needed. All cable configurations in Table One are designed to meet Iridium systemrequirements.Table One—Maximum Cable Lengths and TypesTimes MicrowaveCable Type Loss(dB/m) Max.Length (m) Max.length (ft)LMR 240 0.337319 4.5 14.7LMR 400 0.175363 8.5 28 (Part of Antenna Cable Kit)LMR 600 0.113623 13.2 44LMR 900 0.076893 19.7 65LMR 1200 0.057872 26.2 86LMR 1700 0.043461 35 1151.625" LDF 0.036037 42 138.32.25" LDF 0.030260 50.2 164.7Other configurations of cables besides those listed in Table One can be used as long as the totalinsertion loss for the entire cable run (including any lighting arrestor/surge suppression) is less thanor equal to 2.5 dB over the operating frequency band of 1616 to 1626 MHz. Consult the chosencable manufacturer for more information related to cable performance before installing alternatecables. A replacement of just the center section of coax specified in the table above must have aninsertion loss less than or equal to 1.52 dB over the operating frequency band of 1616 to 1626MHz. These insertion loss specifications assumes the use of Satellite Series Fixed Site Antenna.This antenna meets the antenna gain pattern requirements of the Iridium system.As depicted in Diagram “A”, the optional Satellite Series Antenna Cable kit consists of three cablesand a lighting arrestor/surge suppressor. Since the main coaxial cable is stiff and difficult to dress,two more flexible “jumper” cables are provided to connect both ends of the main cable. A smalldiameter coax cable 0.5 meter (20 inch) long is provided for a flexible linkage between the antennaand the main cable. Another 1.5 meter (59 inch) long small diameter coax cable is provided for aflexible linkage between the 9520 Mobile Phone or 9570 Portable Dock and the main cable. Thelighting arrestor/surge suppressor is installed in series with these cables, as described in Section 8below.
56. Antenna Installation The Satellite Series Fixed Site antenna is provided with two clamps that allow the attachment of theantenna housing to the end of a pole/mast with a diameter of between 19 and 25 mm (3/4 to 1inches). The mast should be secured to a structure such that it can withstand wind loads and othernormal external forces, while being positioned per the guidelines in the Section 5 above. The nutson the clamps should be tightened evenly to a torque of 0.45 to 0.68 N-m (4 to 6 in-lbs.). Excessivetorque will result in long term cracking in the plastic mounting bracket. 7. Cable InstallationCables should be routed and restrained so as to avoid vibration or movement under normalconditions which could result in damage to either the antenna, the 9520 Mobile Phone or 9570Portable Dock, or the coaxial cable connections. Where the cables come in contact with structures,chafing or abrasion of the outer surface of the cable should be prevented. All cable bends must bedone in such a manner as to avoid kinking the cable, and bend radii should follow cable supplier’srecommended limits. All cable connections must be sealed appropriately to prevent moisture andcorrosion damage due to weather exposure.When using the optional Satellite Series Antenna Cable kit, cable connections on the three cables inthe cable system employ either Type “N” connectors, or Type “TNC” connectors. Type “N”connectors should be tightened to a torque of 0.68 to 1.13 N-m (6 to 10 in-lbs.). Type “TNC”connectors should be tightened to a torque o 0.45 to 0.68 N-m (4 to 6 in-lbs.). When using cablesand connectors from other sources, torque specifications for those connectors should follow thosemanufacturers’ recommendations.8. Lightning ProtectionAntennas mounted in fixed installations can be exposed to lightning strikes in certain geographic andclimatological environments. Although it is not considered possible to protect the 9520 MobilePhone, the 9570 Portable Dock, the antenna, or surrounding and/or connected equipment orstructures from damage due to a direct lightning strike, appropriate protection should be employedto minimize equipment and structure damage, and bodily injury due to lightning. Such protection istypically done through the use of specialized lighting arresting/surge suppression components in theinstallation of an antenna system. An example of this is depicted in Diagram “A”.When using the optional Satellite Series Antenna Cable kit, a high frequency surge suppressor issupplied with this kit to attempt to minimize lightning induced damage through lightingarresting/surge suppression. It is intended that this suppressor be installed between either of thesmaller diameter jumper cables and the main coaxial antenna cable. The suppressor should beinstalled at the point nearest to where the coaxial cable enters a building structure, or where thecable first passes close to a grounded structure. Connections to the suppressor should be made inaccordance with the installation instructions supplied by the suppressor manufacturer. If the userchooses to select antenna cables from an alternate source, a device to deal with lightingarresting/surge suppression should still be part of the antenna cable system. If there is anyuncertainty as to what might be the appropriate method to use for lightning arresting and surgeprotection, the services of a professional antenna installer should be employed.
