Antenna Installation - CRT S 8040 Owner's Manual

Antenna Installation

a) Choosing antenna:
– For CB radios, the longer the antenna, the better its results. Your dealer will help you
with your choice of antenna.
b) Mobile antenna:
– Must be fixed to the vehicle where there is a maximum of metallic surface (ground
plane), away from windscreen mountings.
– If you already have a radio-telephone antenna installed, the CB antenna should be
higher than this.
– There are two types of antenna: Pre-regulated antenna which should be used on a good
ground plane (e.g. car roof or lid of the boot), and adjustable antenna which offer a much
larger frequency range and can be used on a smaller ground plane.
– For an antenna which must be fixed by drilling, you will need a good contact between
the antenna and the ground plane. To obtain this, you should lightly scratch the surface
where the screw and tightening star are to be placed.
– Be careful not to pinch or flatten the coaxial cable (as this runs the risk of break down
and/or short circuiting).
– Connect the antenna to location (B).
c) Fixed antenna:
A fixed antenna should be installed in a space as spacious as possible. If it is necessary
for you to fix the antenna to a mast, you need to keep it as per the requirements of the
laws in force (please turn to professional advice).
