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.
-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 (

c) Fixed antenna:
A fixed antenna should be installed in a
space as clear as possible. If it is fixed to a mast,
it will perhaps be necessary to stay it, according to the laws in force (you should seek
professional advice). All AT-5555 antennas and accessories are designed to give
maximum efficiency to each CB radio within the range.
3) POWER CONNECTION
Your RADIO is protected against an inversion of polarities. However, before switching it
on, you are advised to check all the connections. Your equipment must be supplied with a
continued current of 12 volts (
A
). Today, most cars and lorries are negative earth. You can
check this by making sure that the negative terminal of the battery is connected either to
