Midland markets a broad line of high-performance antennas. The dealer who sold you your Midland CB can advise which type is best for you. Where you locate your antenna does make a difference. Some general rules for antenna location that can aid CB performance: 1. Put your mount as high on the vehicle as possible. The higher the proportion of antenna length that is above the roof, the better. If possible, mount the antenna in the center of whatever surface you choose. Keep antenna cables away from noise sources, such as the ignition system, gauges, etc. Make sure you have a solid metal - to - metal ground. 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. 6 Antenna installation.

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.
