Mounting restrictions for certain radio models:
a. For all VHF and UHF models, the 1/4 wave antenna should be
mounted only in the center area of the roof, not on the trunk lid, to
ensure compliance with RF Energy Safety Standards.
b. Ensure that the antenna cable can be easily routed to the APX VA.
Route the antenna cable as far away as possible from any vehicle
electronic control units and associated wiring.
c. Check that the antenna location for any electrical interference.
d. Ensure that any transmitting radio antennas on this vehicle are
separated from each other by at least 3 feet (92 cm). See Figure 3.
Figure 3: Multiple Antenna Separation
e. The minimum distance between the antenna and the radio or
accessories should be at least 3 feet (92 cm).
Note: Any two metal pieces rubbing against each other (such as seat springs,
shift levers, trunk and hood lids, exhaust pipes, and others) in close
proximity to the antenna can cause severe receiver interference.
Mini-UHF Connection
Note: The RF connector (J3) on APX VA console is a mini-UHF jack, and must
be mated with either an antenna mini-UHF plug (P3) or an appropriate
adapter (part numbers: 5880367B21 [mini-UHF-to-N]; 5880367B22
[mini-UHF-to-UHF]; or 5880367B24 [mini-UHF-to-TNC]).
To ensure a secure connection of an antenna cable’s mini-UHF plug to
an APX VA mini-UHF jack, their interlocking features must be properly
engaged. If they are not properly engaged, the system will loosen.
Using a tool (pliers or wrench) will not overcome a poor engagement,
and is not recommended.
If these conditions cannot be satisfied, then mount the antenna on
the roof top.
