What does a ground plane do for a CB antenna?
A ground plane for a CB radio antenna is the metal surface required below the antenna. In mobile applications, the vehicle body/frame acts as the ground plane (reflective unit). The metal surface enables the signal generated when transmitting to reflect off the surface and travel into the atmosphere.

Does CB antenna need a ground plane?
A Groundplane is needed for any CB antenna to work, without it the antenna will not transmit very well and your SWR reading will probably be very high.
How big should ground plane be?
In order to be effective, a ground plane needs to have a radius of at least a quarter of the wavelength of the radio waves the antenna is transmitting. For GNSS and GPS, which broadcast at either 1575.42 MHz or 1227.60 MHz, this means a ground plane with a radius of around 5 cm.
What is the strongest CB antenna?
Fiberglass antennas are usually the best choice for 4×4 and off-road drivers. They’re the most durable type of antenna and hold up best to the rigors and abuse of off-road use.
How big does a ground plane need to be?
To function as a ground plane, the conducting surface must be at least a quarter of the wavelength (λ/4) of the radio waves in radius. In lower frequency antennas, such as the mast radiators used for broadcast antennas, the Earth itself (or a body of water such as a salt marsh or ocean) is used as a ground plane.
What is the best way to ground a CB antenna?
Worth mentioning again is that the most important part of getting a good ground is to attach the ground to metal rather than plastic or other materials. You also need to place the hot side of the coaxial cable to the antenna itself. The ground is the side that comes from the shield of the coaxial cable.
