MAXIMUM RANGE

The maximum range and quality of
CB transmissions vary depending on
these conditions:
• The type and quality of antenna
used
• The height of the antenna's
mounting location — the higher
PUSH TO the antenna, the better the sig-
nal's range
• The
mountains and tall buildings limit
the range
• Weather conditions
• The current setting of
your CB
• The number of nearby CBs
operating on the same channel
• Standing Wave Ratio (SWR)
between the antenna and the
CB. You can check the SWR
between the CB and a mobile
antenna using an SWR tester
(Cat. No. 21-523). Follow the
instructions supplied with the
SWR tester and the mobile
antenna to change the SWR, if
necessary.
