[. . . ] 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. Mounting the main unit. Step 1: Loosen the retaining knobs on each side of the mounting bracket to give enough space for the unit to slide between the two bracket arms. Step 2: Position the main unit between the bracket arms in line with the retaining knobs. Set the height and angle for optimum operating comfort and accessability. Step 3: Tighten the retaining knobs. 5 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. 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. Follow the manufacturer's installation instructions carefully. Warning: Never operate your CB radio without attaching an antenna or with a broken antenna cable. Safety notice: The antenna used for this radio must be installed to provide a separation distance of at least 20cm (8 in. ) from all persons and must not be colocated or operating in conjunction with any other antenna or transmitter. 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. You can expect to maintain maximum transmitting/receiving performance in flat, open country. [. . . ] You do not need to return accessory items (brackets, screws, power cord, antenna, etc. ) unless they may be directly related to the problem. Include a photocopy of the bill of sale or other proof of purchase showing the date of sale.
