Install and Connect GPS Antenna
The radio is equipped with a GPS receiver which requires connection to an externally-mounted GPS
antenna if the GPS functions will be utilized.
The SMR/GPS combo antenna kit includes a GPS antenna built into the base of the mobile antenna. No
extra holes are required for the GPS cable when using this antenna. The antenna must be kept at least six
(6) inches away from any other antenna mounted on the vehicle and have at least six inches of surface
ground plane beneath it.
1.
Once the mounting location is selected, refer to the antenna manufacturer’s mounting and testing
instructions for installation guidance. If necessary, contact M/A-COM’s Technical Assistance Center
(see page 13 for contact information).
2.
Route the cable from the GPS antenna to the rear of the radio. The cable should be kept out of casual
contact from persons within the vehicle.
3.
Connect the GPS antenna cable’s SMA plug-type (male) connector to the radio’s SMA receptacle-
type (female) “pigtail” type RF connector at the rear of the radio. Mate the two connectors and turn
the plug clockwise. Tighten with a pair of slip-jaw pliers.
NOTE
Do not attempt to alter the length of cable from the GPS antenna. The SMA connector
on the end of the antenna cable is not field-replaceable. Tie and stow excess cable as
necessary.
