USING THE CB AS A
BASE STATION
Although this CB is designed mainly
for mobile use, you can also use it as
a base station with an AC power
source. For base station installation,
you need the following items (all avail-
able at your local RadioShack store):
• 12-volt DC power supply (such as
Cat. No. 22-504)
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 in-
cluded with the power supply.
• Base station antenna (such as
Cat. No. 21-969)
• Coaxial antenna cable and con-
nectors
Follow these steps to install the CB as
a base station.

frame or battery (–)
1. Mount the base station antenna

ual.

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 con-
tact overhead power lines. If the
antenna touches the 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.
2. Route the antenna cable to the
CB, then connect the antenna to
the jack on the back of
ANTENNA

3. Connect the CB's black power
wire to the negative (–) terminal
on the DC power supply.
4. Connect the CB's red wire, with
the in-line fuse, to the positive (+)
terminal on the DC power supply.
5. Connect the DC power supply to a
standard AC outlet.
