[. . . ] Then disconnect the negative lead from the battery to prevent short circuits that can occur during wiring. Do not connect this transceiver to positive ground electrical systems. Step 2: With negative ground A. connect the positive (RED WIRE) the one with in-line fuse holder to either the ( a ) fuse block, ( b ) cigarette lighter, or ( c ) directly to the positive post on your battery. 4 Usually, the fuse block is the most convenient connecting point. It is also possible to connect to the Accessory terminal on the fuse block or ignition switch, so that your CB automatically goes off when the ignition goes off. Then tightly connect the ground (BLACK WIRE)directly to the vehicle's metal frame. A good direct metal-to-metal ground is essential for optimum performance. Installations using the cigarette lighter socket for power require an extra ground wire from the radio chassis to the vehicle if the radio is not fastened to a grounded part of the vehicle. Installation of microphone hanger. Mounting holes are provided on the microphone hanger bracket. The bracket can be attached to the vehicle dash, or other convenient location. Antenna: How to select, position install and tune the right one for you. Basically, you may choose from two types of mobile CB antennas full-length whip and loaded whip - and a variety of of mounts (depending on where you locate your antenna). 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. 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. 5 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. 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 will 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. You can buy an SWR meter separately or have your antenna checked by your Midland CB Dealer's service department. Factors affecting CB range Essentially, they are the same influences that optimize or limit AM and FM broadcast signals. Terrain: Hills, valleys and buildings naturally interrupt and shorten CB signals. In short, any thing that is between you and the person you want to talk to can shorten your CB range.
