INSTALLATION
CB ANTENNA
10
For the most reliable operation and
maximum range, Cobra recommends using
a vertically polarized, quarter–length whip
antenna (illustration 1).
Shorter, loaded-type whips are adequate
when maximum range is not required
(illustration 2).
NOTE: Mobile installations (cars, trucks,
boats, etc) should be made only with a
non-directional antenna system.
• A standard antenna connector (Type
SO-239) is provided on the Connector Box
for easy connection to a standard PL-259
cable termination.
• Cobra antenna models are
recommended; see your local CB dealer or
order directly from Cobra. See order form
on page ??.
• For maximum efficiency in boat
installations, a ground plate is required,
unless the vessel has a steel hull. Consult
your CB dealer for information regarding
an adequate grounding system.
SPEAKERS/NOISE INTERFERENCE
1. Mount external speaker in desired location as shown
2. Plug into the back of the Connector Box
*The external speaker should have 4-8 ohms impedance and be able to
handle at least 4 watts.
IGNITION NOISE INTERFERENCE
The alternator and ignition system in your vehicle may limit your ability
to receive low signal levels.
Other noise interference can be the result of several different installation
variables. Consult your Cobra dealer or a 2-way radio technician to help
locate and correct the source of severe noise interference.
SOUNDTRACKER
SYSTEM
®
While previous systems only "blanked out" or limited noise in higher
sound frequencies, the revolutionary new SoundTracker
reduces noise while leaving the signal intact in the reception mode. In the
transmission mode, it actually strengthens the signal, providing you with a
significant reduction in noise.
