7.2 RF ANTENNA INSTALLATION PROCEDURES
An antenna must be installed before completing the radio installation.
Section 4 lists the mobile radio antennas available for use with the radio. As presented in the previous
section, various mounting locations exist. Optimal performance is achieved via a rooftop antenna mounted
in the direct center of the motor vehicle’s roof.
7.2.1 Installing Antenna Mounts AN-125001-002, -004, and -006
These NMO style antenna mounts can each be used with several different antenna elements. Only limited
access under the mounting location is typically required. The installation procedure is presented in Section
7.2.1.3.
7.2.1.1 Standard Antenna Mounts AN-125001-002 and -006
This standard ¾-inch NMO antenna mount requires a ¾-inch hole in a relatively flat area of the vehicle
body, with a vehicle metal thickness of between 0.020 and 0.040 inches.
7.2.1.2 Thick-Roof Antenna Mount AN-125001-004
This thick-roof NMO antenna mount uses a -inch or a ¾-inch mounting hole in a relatively flat area of
the vehicle body, with a vehicle metal thickness of between 0.040 and 0.1875 inches (
