2.4.1

Selecting an Antenna Site/Location on a Metal Body Vehicle

1. External installation – Check the requirements of the antenna supplier and install the
vehicle antenna external to a metal body vehicle in accordance with those requirements.
2. Roof top – For optimum performance and compliance with RF Energy Exposure regulations,
mount the antenna in the center area of the roof.
3. Trunk lid – On some vehicles with clearly defined, flat trunk lids, the antennas of some radio
models (see restrictions below) can also be mounted on the center area of the trunk lid. For
vehicles without clearly defined, flat trunk lids (such as hatchback autos, sports utility
vehicles, and pick-up trucks), mount the antenna in the center area of the roof.
Before installing an antenna on the trunk lid,
- Be sure that the distance from the antenna location on the trunk lid is at least 85 cm (33
inches) from the rear seat head-rest to ensure compliance with RF Energy Exposure regu-
lations.
- 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.

4. Mounting restrictions for certain radio models.
NOTE: Do not cut antenna cables to ensure compliance with RF Energy Exposure regulations
NOTE:
5. Ensure that the antenna cable can be easily routed to the radio. Route the antenna cable as
far away as possible from any vehicle electronic control units and associated wiring.
6. Check the antenna location for any electrical interference.
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.

Draft
To assure optimum performance and compliance with RF Energy
Exposure regulations, these antenna installation guidelines and
instructions are limited to metal-body vehicles with appropriate ground
planes and take into account the potential exposure of back seat
passengers and bystanders outside the vehicle.
