This limits the application to large trucks your typical pickup is too narrow to provide 9 foot spacing. For proper co-phasing, the antennas should be mounted approximately 9 feet apart. This type of configuration provides increased range to the front and rear, and reduced range to the sides. They are typically mounted using mirror mounts. The glass mount antenna is a no-ground-plane antenna, and is therefore suitable for fiberglass vehicles and boats.ĭual antennas (also called co-phased antennas) are popular, more for looks than for performance. But it does offer a solution if other mounting methods are not acceptable. Because of the short antenna and some signal loss through the glass, this type of antenna is one of the poorest performers. The antenna should not be mounted over any metallic tint or over defroster lines. The antenna is mounted on the outside with double sided tape, and a small box is mounted in the exact same spot inside the vehicle with double sided tape. This type of antenna is short, and looks similar to a cellular phone antenna. It is a permanent mount, and should not be mounted to any glass that rolls down or swings open. Or the cable can be brought in through the window.Ī glass mount antenna mounts to any window on the vehicle. After mounting, the antenna cable is brought inside the vehicle and the door is closed on the antenna. Actually, most modern cars have done away with rain gutters to improve aerodynamics. A minimum 16 gauge wire is recommended, connected to the nearest ground point on the chassis.Ī gutter mount antenna clamps onto the rain gutter above the door. If the door is fiberglass, it will be necessary to run a ground wire to the antenna clamp. In addition, it is important that the antenna clamp gets grounded to the vehicle. Plastic mirrors won't work, the mirror must have a metal bracket. Popular on trucks, the mirror mount antenna clamps onto the mirror bracket.
ANTENNE CB INSTALL
Bumper mounts are more difficult to install on vehicles with plastic bumpers. If you use a fiberglass antenna, choose one that extends at least a foot above the roof of the vehicle. It will be necessary to drill a hole for the mount. You can also mount a fiberglass antenna to the bumper. This is the place to choose if you want to use one of the really long whips. It can also be mounted along the side edge of the trunk lid. It is usually mounted along the front of the trunk lid, just behind the rear window. The trunk lip mount clamps on the edge of the trunk lid. Magnet mount antennas are quick to install, easy to remove, and are easily transferred from one vehicle to another. Or the cable can be brought in through the window. The cable is brought inside the car, and the door or trunk lid is closed over the cable. The antenna can be mounted on the roof or the trunk lid, but roof mounting provides better performance. The magnet has a plastic covering so that it does not scratch the paint. A large magnet keeps the antenna on the car. Try browsing on the internet.Ī magnet mount antenna means just what it says. Base station antennas are available from a variety of vendors. Since the cable run can be rather long, it is best to use RG8 cable which has low loss.
ANTENNE CB TV
And any kind of indoor antenna will get truly lousy range.īase-station antennas use the same type of mounts as TV antennas. Mobile antennas are designed strictly for vehicles and will not work properly for base-station use. If you are using a CB radio in your home, you will need a base-station antenna mounted on your roof. The next step in choosing an antenna is choosing a mounting method. If you need a no-ground-plane antenna, then you are done with this document (but you can skip below to the glass mount antenna). They typically mount using some kind of bracket, except for the glass-mount type. There are not many choices of no-ground-plane antennas, so you will have to work with the styles you find available. The cable is specially matched to the antenna. Please note that it is important not to modify or change the cable that comes with the antenna. You can find these antennas at Radio Shack and places that sell boating and RV accessories. A no-ground-plane antenna is specially designed for these applications.

Boats and fiberglass vehicles lack a proper ground plane.

Most CB antennas require a large metal surface (called a "ground plane") in order to work properly. If you are mounting an antenna to a boat or fiberglass RV, you need a special type of antenna called a "no-ground-plane" antenna. The first step in choosing an antenna depends on the type of vehicle you have. This document describes the various styles of CB antennas.
