Mount the Antenna at a suitablelocation on the vehicle, and route theAntenna Cable inside the vehicle forconnection to the Radio.The Antenna (Item 2) that is included in the kitmust be mounted by drilling a hole. The optimalposition of the antenna is in the direct center ofthe roof of the vehicle. Refer to AntennaMounting Configurations for requirementsnecessary to follow when selecting the propermounting area for the antenna. Also, refer to theantenna manufacturer’s mounting and testinginstructions included in the Antenna Assembly kitfor installation guidance once the mounting areais determined.Route the cable from the Antenna (Item 2) to therear of the Radio out of the way of casualcontact. Install the Mini-UHF connector of thecable to the mating connector at the rear of thecable by tightening until finger-tight. It isimportant that this connector is tight to preventRF leakage from occurring, but not too tight thatdamage occurs.Do not connect the antenna cable to the Radiountil satisfactory completion of testing into adummy load (refer to Testing Into a DummyLoad).6. If an optional GPS unit is included inthe Radio, the GPS Antenna needs tobe connected to the Radio.Connect the SMA connector of the GPS Antenna(Item 11) cable to the SMA connector on the rearof the Radio and route the cable out of the way ofcasual contact. The GPS Antenna is to bemounted on the roof of the vehicle with one ofthe 3 mounting configurations: Show-Mount, NoShow-Mount, and Magnetic Mount. The Antennamust be kept at least 1 foot from any otherantenna mounted on the vehicle and have atleast 6 inches of ground plane beneath it.7. Prepare for connecting the power tothe Radio through the vehicle’sfirewall.Plan the cable route carefully, using an existingaccess hole through the engine firewall ifpossible. Alternatively, drill a new holeapproximately 3/8" in diameter and install arubber grommet to protect the cable.NOTE Improperinstallation of the antenna maylead not only to poor radioperformance, but to harmfulexposure as well. See AntennaMounting Configurations below.

The Fuse for Radio power must beinstalled in-line with raw batteryvoltage.Strip one end of the wire included in the Fuse Kit(Item 3) and crimp the terminal lug onto it. Cutthe wire to a length of about 6 inches and stripthe end to a length indicated by the gauge on thefuse holder. Insert this end into the fuse holderuntil the wire cannot go any further and crimp theconnection to the fuse holder. Use heat-shrinktubing to protect the connection from foreignmaterials. Connect the remaining wire in a similarfashion to the other end of the fuse holder.Connect the terminal to the vehicle’s battery inthe engine compartment. Route the wire througha wire loom and pass it through the firewall usinga grommet to ensure the wire is not damaged.9. Prepare the ground and senseconnections prior to applying power tothe Radio.Connect the DC Power Cable (Item 4) to the 3-pin connector at the rear of the Radio. Locate achassis ground close to the Radio and strip backany jacket insulation around the wires to allow forthe shortest distance of the black wire. Cut thenegative (black) wire as short as possible, strip it,and crimp the terminal to it. Screw it into thechassis ground, ensuring a reliable metal-to-metal contact.Connect the sense (white) wire of the DC PowerCable (Item 4) to an appropriate terminal toconnect to a fused ignition sense in the fuse boxand route the excess wire out of the way ofcasual contact.10. Apply the DC power connection to theRadio.NOTE Unlike many mobileradios, the OpenSky® Mobile Radiopowers up immediately uponapplication of DC power.Using a pigtail, butt-splice, or solder-sleeve,connect the positive (red) wire of the DC PowerCable (Item 4) to the fuse wire (Item 3) and routethe excess wire out of the way of casual contact.11. Test the output of the installed Radiointo a dummy load to verify that itmeets specifications.Refer to Testing Into a Dummy Load underTesting below for the procedure.

Connect the Antenna and test theRadio’s forward and reflected powerto verify transmission performance.Refer to Testing With the Antenna under Testingbelow for the procedure.13. Complete the installation byorganizing, securing, and checking allcables and components.Take whatever steps are practical to make theinstallation neat and functional for the Radio’suser. Organize and secure all cables; make sureall connections are tight.TESTINGThis section sets forth procedures to verify the performance of the installed radio.Testing uses a wattmeter (or, alternatively, a VSWR meter) to measure RF power.There are three procedures in this section: Changing Operating Modes, Testing Intoa Dummy Load, and Testing With the Antenna. Note that while the radio’s normaloperating mode for voice or data communications is OpenSky® Trunking Protocol(OTP), the radio must be operating in OpenSky® Conventional FM (OCF) mode fortesting. Follow the procedure under Changing Operating Modes to switch betweenthe OCF and OTP modes.Note also that the accuracy of test results depends on a radio power source in therange of 13.8–16 volts DC at greater than 8 amps. Make sure the vehicle’s battery isfully charged by running the engine for a few minutes before the test, and keep theengine running during the test procedures.Test Equipment CommentsWattmeter Bird Electronic Corporation Model 43 orequivalent, with N-Series female connectors onboth the input and output sidesAs an alternative to using a wattmeter, aVoltage Standing Wave Ratio (VSWR) meter,Bird Electronic Corporation Model 4391A orequivalent, can be used to carry out therequired RF (radio frequency) power testing.Slug For use with the wattmeter; rated power of 25watts and frequency range appropriate to the800 MHz output of the OpenSky® radio (BirdElectronics Element APM-25E (25 watts, 400–1000 MHz) or equivalent)

Using Table II as a guide fordetermining the best possible mounting configuration in order to reduce humanexposure, there are three possible locations on a vehicle where the antenna can bemounted, described as follows:Rooftop Center (Items 1 and 2 above) The center of the roof of a vehicle is the optimallocation for the rooftop antenna. The mounting area under the antenna must be a flat,metallized ground plane, and it must be located directly in the center of the roof. Ifother obstructions, such as a light bar or another antenna, prevent the antenna frombeing mounted in the direct center of the roof, the antenna should be mounted,preferably, a minimum of one foot away from the obstruction, but in the middle of theroof with respect to the left and right sides of the vehicle.Trunk-Lid Center (Items 1, 2, and 3 above) Certain vehicles do not allow for theantenna to be placed in the center of the roof. In this case, the next optimal location forthe antenna is in the center of the trunk lid. Again, the mounting area under theantenna must be a flat, metallized ground plane, and it must be located directly in thecenter of the trunk lid. There are no other preferable solutions for mounting thisantenna if other obstructions prevent the antenna from being mounted in the directcenter of the trunk lid.Trunk-Lip Center (Items 3 above only) Only the third choice of antennas above allowsfor a configuration for a trunk-lip mount for the antenna. In this case, the antenna ismounted on the top lip and in the direct center of the trunk lid. Again, there are noother preferable solutions for mounting this antenna if other obstructions prevent theantenna from being mounted in the direct top center of the trunk lid.Changing Operating Modes (Preliminary)Actions Notes1. Press the UP ARROW button on thenavigation pad repeatedly until themessage “MODE” appears on the unit’sdisplay, then press the SELECT button.The buttons controlling the radio’s operatingparameters are on the left side of the front of theradio.2.
