Before installing an antenna on the trunk lid,
• Ensure that the distance from the antenna location on the trunk lid will
be at least 36 inches (90 cm) from the front surface of the rear
seat-back to ensure compliance with RF Energy Safety Standards.
• Ensure that the trunk lid is grounded by connecting grounding straps
between the trunk lid and the vehicle chassis.
If these conditions cannot be satisfied, then mount the antenna on
the roof top.
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 5.
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.
