Midland Radio CB-1 Manual Do Utilizador

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�

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�

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�

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�
