of 1 on the SWR meter's top scale (this is obtainable
mostly under radio laboratory test conditions).
A 1.5:1 to 2:1 SWR ratio is excellent for most mobile
CB antenna applications.
Antenna installations in-the-
field will probably show higher SWR meter readings.

PERFORMANCE
Perfect match between the
antenna and cable length
to the CB radio transmitter's
RF output power.
The antenna/cable system
is an outstanding match
with this CB transmitter's
RF output power; ideal for
most CB installations.
The antenna/cable system
with this CB transmitter
will perform to spec under
most normal conditions.
Requires antenna system's
mounting hardware or
ground inspected; or the
antenna system adjusted,
or replaced.
