signals.
Terrain : Hills, valleys and building naturally interrupt and shorten CB signals. In short,
anything that is between you and the person you want to talk to can shorten your CB
range. You can expect to maintain maximum transmitting/receiving performance in
flat, open country.
Weather : You can expect that CB range will be reduced – perhaps drastically – in
times of atmospheric disturbance, such as in a thunderstorm or heavy snow.
Sunspots too are known to adversely affect CB performance.
Noise :
A common source of excessive noise is the ignition system. In many vehicles today
the electric fuel pump is another possible source of noise. If you suspect this is true,
turn off the ignition. With the CB in receive mode the noise is no longer present this is
a source of the noise. In some cases the noise can be reduced or eliminated by
making sure the CB radio chassis is grounded. This is in addition to the power cord.
In extreme cases, additional grounding of components may be necessary.
