WebAug 17, 2010 · The average mag-mount antenna gets its “ground” from the magnetic attraction between the mount and the metal of the car body. This is nowhere near the quality of a good, solid ground connection to the body. We are relying here on the mount, the paint on the car, and the metal underneath to form a “capacitive ground connection”. WebMar 30, 2024 · You should ground the shield of the coax before or at the connection point to the balun, not between the balun and antenna.

How To Ground A Magnetic CB Antenna - Purdy Lounge
WebThe ideal length for a CB (Citizens Band) radio antenna is a full quarter wave. This means that the antenna should be 1/4 of the wavelength of the frequency you’re using. For example, on a channel at 27 MHz, the wavelength would be 11 meters and the ideal antenna length would be 2. 75 meters (just under 9 feet). WebIf you’re using a standard CB antenna (i.e., anything except a no ground plane, or NGP, kit), you’ll need to make sure your antenna mount is solidly grounded to the vehicle’s chassis. A bad ground will result in an un-tunable antenna and sky-high SWR levels. To ensure a good ground, check that your mount has a direct metal-on-metal ... WebAug 30, 2024 · The first step in choosing an antenna depends on the type of vehicle you have. 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.
