8.2.5 Connecting the Mobile Antennas
1. Label the radio-end of each antenna cable. The cable from the rooftop-mounted antenna (highest of
the two) should be labeled “MRU Antenna” and the cable from the trunk-mounted antenna (lowest of
the two) should be labeled “LBPA Antenna.”
2. Route each antenna cable from the antenna to the rear of the respective radio. Remove headliner
panel, other interior panels, etc., as necessary. Keep each cable out of casual contact areas from
persons within the vehicle. Tie and stow as necessary to protect the cables.
Use the full length of coaxial cable included with each antenna. Never cut the cable to a
shorter length, but rather coil any excess. Reducing the length of cable increases the
output power radiated by the antenna, thereby exceeding the Maximum Permissible
Exposure (MPE) allowance regulated by the FCC.
The MRU and LBPA antennas are not interchangeable. Therefore, label the radio-end
of each cable for future reference, as described in step 1.
3. Using an appropriate crimp tool, crimp the supplied TNC RF connector to the end of each antenna
cable. See Figure 8-6 for crimping instructions.

4. Connect each antenna cable’s TNC plug-type (male) connector to the respective radio’s TNC
receptacle-type (female) RF connector at the rear of the radio. The MRU antenna cable (labeled
“MRU Antenna”) must be connected to the “MB ANT” connector on the rear of the radio. The LBPA
