CB ANTENNA INSTALLATION
For the most reliable operation and
maximum range, Cobra recommends
using a vertically polarized, quarter
wavelength whip antenna (illustration A).
Shorter, loaded-type whips are adequate
when maximum range is not required
(illustration B).
NOTE: Mobile installations (cars, vans,
lorries, 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.
• For maximum efficiency in boat
installations, an earthing plate is required,
unless the vessel has a steel hull. Consult
your CB dealer for information regarding
an adequate earthing system.
• Be sure that the antenna is properly
connected and tuned (SWR) to the radio
before transmitting. Prolonged transmitting
without an antenna, or use of a poorly
matched antenna, could cause damage to
the transmitter.
