Where you locate your antenna does make a difference.
Some general rules for antenna location that can aid CB performance:
1. Put your antenna mount as high on the vehicle as possible.
2. The higher the proportion of antenna length that is above the roof, the
better.
3. If possible, mount the antenna in the center of whatever surface you
choose.
4. Keep antenna cables away from noise sources, such as the ignition
system, gauges, electric fuel pumps, etc.
5. Make sure you have a solid metal - to - metal ground.
6. Exercise care to prevent cable damage.
Essentially, you have five location choices: the roof, gutter, rear deck, front
cowl or rear bumper. Where you decide to locate your antenna will
determine the type of antenna you install. Again consult your Midland CB
dealer for advice and guidance, and measure your needs against the
attributes of the various Midland antenna models he carries. Weather radio
performance may be degraded by use of a base loaded antenna.
Antenna installation.
Follow the manufacturer’s installation instructions carefully.
Warning: Never operate your CB radio without attaching an antenna or with
a broken antenna cable. This can result in damage to transmitter circuitry.
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.
