34 Radio installation
The cable should be routed in a manner that mini-
mizes coupling into the electronic control systems
of the vehicle.
Avoid sharp bends in the cable. These distort the
cable and alter its electrical characteristics.
Mount the antenna at a location such that no person or
persons can come closer than 0.9m (35 inches) to
the antenna.
For 25W radios, the radio must be installed using an
externally mounted antenna with a gain of either a
2.15dBi or 5.15dBi gain.
For 40W/50W radios:
— VHF radios must be installed using an antenna
mounted centrally on the vehicle roof, with a gain of
2.15dBi or 5.15dBi.
— UHF radios must be installed using an antenna either
mounted centrally on the vehicle roof with a gain of
2.15dBi or 5.65dBi, or mounted centrally on the
trunk with a gain of 5.65dBi.
Run the free end of the coaxial cable to the radio's
mounting position and cut it to length, allowing 20 -
30cm (8 - 12 inches) excess.
The cable should be protected from engine heat,
sharp edges and from being pinched or crushed.
Terminate the free end of the cable with the BNC or
mini-UHF plug.
