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 mus t be
installed properly by trained personnel. The following must be
observed during installation.
The positive power connection should be made directly to the
batter y 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 possible. 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 interference
between the communications equipment and the vehicle’s elec-
tronic systems.
