INSTALLATION
SELECTING A
LOCATION
Choose a location for your CB that is
near a standard AC power outlet and
your antenna installation and away
from sources of electrical noise.
CONNECTING AN
ANTENNA
An antenna is an important part of
your CB installation. Choose and in-
stall the antenna with care.
Consider the following when you in-
stall the antenna:
• Mount the antenna as far as
possible from soures of electri-
cal noise (power lines, trans-
formers, ignition systems,
electrical motors, and so on) and
keep the antenna's cable away
from these noise sources.
• Provide a good ground for the
antenna with UL-listed compo-
nents.
• Be sure the antenna cable's
shield is securely connected.
• Mount the antenna as high as
possible without exceeding 60
feet above the ground or 20 feet
higher than the highest point on
a building.
• For the best performance, the
antenna must be tuned (see the
instructions provided with the
antenna) and positioned verti-
cally.
Select an antenna with a PL-259
connector. This type of antenna
works most efficiently as a base sta-
tion antenna. For example, a
1
/
2
-
wave base station antenna (Radio
Shack Cat. No. 21-967) is a high-effi-
ciency antenna that has omni-direc-
tional characteristics. You can use
this type of antenna for medium and
long-range communications.
Use coaxial cable with an impedance
of 50 ohms to connect the antenna to
your CB. We suggest you use RG-
58/U for lengths under 10 feet, or
RG-8/U for longer lengths, and keep
the length of the antenna cable to a
minimum.
Once you select the antenna, mount
it following the instructions supplied
with it. Then route the cable to the CB
and connect the cable to the ANT
connector on the back of the CB.
