mind that, for the best performance, you
should mount the antenna:

home or building
• as far as possible from source of
electrical noise
• vertically
Once you choose an antenna, follow its
mounting instructions. Then route the
cable to the CB and connect the cable to

edges or moving parts which might
damage the cable.
• Do not run the cable next to power
cables or other
cables.

ing Wave Ratio (SWR) using an SWR
meter (such as Cat. No. 21-523).
Follow the instructions supplied with the
SWR meter and antenna to adjust your
antenna's SWR to the lowest possible
value. SWR values of 2.0:1 are general-
ly acceptable, with readings of 1.5:1 or
