INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into
this vehicle’s electronic system to provide immunity
to radio frequency signals. Mobile two-way radios
and telephone equipment must be installed prop-
erly by trained personnel. The following must be
observed during installation.
The positive power connection should be made
directly to the battery and fused as close to the
battery as possible. The negative power connection
should be made to body sheet metal adjacent to the
negative battery connection. This connection
should not be fused.
Antennas for two-way radios should be mounted on
the roof or the rear area of the vehicle. Care should
be used in mounting antennas with magnet bases.
Magnets may affect the accuracy or operation of
the compass on vehicles so equipped.
The antenna cable should be as short as practical
and routed away from the vehicle wiring when pos-
sible. Use only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio
to ensure a low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater
than normal may require special precautions.
All installations should be checked for possible in-
terference between the communications equip-
ment and the vehicle’s electronic systems.
