Antenna Installation
Follow the manufacturer's installation instructions carefully�
Warning: Never operate your CB radio without attaching an antenna or with a broken
antenna cable� This will result in damage to transmitter circuitry�
Safety notice: The antenna used for this radio must be installed to provide a
separation distance of at least 8 in� (20cm) from all persons and must not be
co-located or operating in conjunction with any other antenna or transmitter�
Tuning Your Antenna
Some antennas are factory tuned� However, performance can usually be improved by
slightly lengthening or shortening the antenna using a Standing Wave Radio (SWR)
meter� For the exact procedures to be used, refer to the antenna manufacturer's
installation manual�
You can buy an SWR meter separately or have your antenna checked by your Midland
CB Dealer's service department�
Factors affecting CB range
Essentially, they are the same influences that optimize or limit AM and FM broadcast
signals�
Terrain: Hills, valleys and buildings 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 if the noise is no longer present then
this is the 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�
