Tuning your antenna.
Some antennas are factory tuned. However, performance can usually be
improved by slightly lengthening or shortening its length, using a Standing Wave
Radio (SWR) meter. For the exact procedures to be used refer to the antenna
manufacturer’s installation manual.
You can buy an SWR meter separately or have your antenna checked by your
Midland CB Dealer’s service department or a two-way comm shop.
