Making your ain CB mobile antenna requires a basic understanding of the frequency used past CB send and receive radios. The wavelength of the 27-MHz CB band is a little over 17 feet, or 204 inches; to send and receive CB, use two halves of this continuing wavelength, or ii 102-inch lengths of copper wire. Insulate and footing these two lengths of wire, connect them to your CB radio, and then mount them to the highest user-friendly point on your vehicle.

Materials

For the trunk of the antenna, use a 55- to 58-inch-long rod of whatsoever non-conductive material. Information technology should exist sturdy enough to stand up upwardly to a stiff breeze. A solid quarter-inch cobweb glass shaft is platonic; aluminum, PVC or even wood will also work. For manual, use two lengths of thin copper wire that are 110 inches long; the eight extra inches are for attachment. Apply two minor insulation eggs to isolate either end of the copper wire, or employ duct record to wrap the finished antenna. Use a length of RG-8 coaxial cable long enough to stretch from the spot where y'all'll mount the finished antenna to the location of your CB radio. Attach the proper connector -- generally an RP-SMA-Female person -- to the other stop after pulling the cable to the CB radio.

Tools

Having a quality soldering atomic number 26 is important, as is a soldering stand to concord the antenna components while yous're soldering. You lot need a roll of electronic solder, duct tape, besides as a roll of double-sided tape to hold the copper wire in place while wrapping it around the antenna rod. A standard toolset -- including screwdrivers, pliers and assorted clamps -- can also come up in handy.

Assembly

Wrap four inches of each end of the 110-inch copper wires through each end of the 2 insulator eggs, and so twist the wires to make a strong mechanical contact. Solder each twist to brand a potent electrical contact. Loop the double-sided tape around the shaft of the antenna rod from acme to bottom. A second set of easily is very helpful in this and the post-obit tasks. Starting at one stop of the antenna rod, wrap the copper wires around the shaft, keeping the two wires from touching each other. Cover the rod in duct tape either lengthwise or with a screw wrap, making certain all parts of the rod are covered. Strip ane finish of the RG-8 cablevision, and and then solder the center lead to one side of the insulator egg and the braided silver ground wire to the other. Cover the upper stop of the rod with duct tape, leaving about four to five inches available for the mounting hardware.

Placement

Ideally, mountain the antenna at the highest bespeak on your vehicle. If this is inconvenient, any metallic surface will do. If you use a magnetic mount, run a ground wire from the braided silver wire of the RG-eight cable to any part of the vehicle chassis. A broad variety of antenna mounts is available online or at your local electronics retailer.
