Be
sure the antenna
is
properly connected
to the radio before transmitting. Prolonged
transmitting without an antenna, or
use
of
a poorly matched antenna, could cause
damage to the transmitter.
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
S0-239)
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, a
ground
plate is required,
unless the vessel
has
a steel
hull.
Consult
your
CB dealer
for
information
regarding
an adequate
grounding
system.
