USING THE CB AS A BASE 

STATION

Although this CB is designed for mobile use, you can use it 
as a base station with an AC power source. Your local 
RadioShack store carries a wide selection of base station 
antennas, coaxial antenna cable, connectors, and base 
station power supplies. For base station installation, you 
need the following items:

• a 12-volt DC power supply that can supply at least 1.5 

amps. 

• base station antenna.

• coaxial antenna cable and connectors.

1. Mount the base station antenna 

as described in its owner’s 
manual. 

2. Connect the antenna cable to the

 

ANT.

 jack on the back of the CB.

3. Connect the CB’s black 

POWER

 

wire to the negative (–) terminal 
on the DC power supply. 

4. Connect the CB’s red 

POWER

 wire to the positive (+) 

terminal on the DC power supply.

5. Connect the DC power supply to a standard AC outlet.

 CAUTION 

Most 12-volt DC power supplies 
plug into a standard AC outlet to 
produce DC power. Before 
connecting your CB to a 12-volt DC 
power supply, read and follow the 
instructions included with the 
power supply.

 WARNING

Use extreme caution when you 
install or remove a base station 
CB antenna. If the antenna starts 
to fall, let it go. It could contact 
overhead power lines. If the 
antenna touches a power line, 
contact with the antenna, mast, 
cable, or guy wires can cause 
electrocution and death. Call the 
power company to remove the 
antenna. DO NOT attempt to do 
so yourself.
