Radio antenna theory In telecommunication, a ground plane is a flat or nearly flat horizontal conducting surface that serves as part of an antenna, to reflect the radio waves from the other antenna elements. The plane does not necessarily have to be connected to ground.Click to see full answer. Consequently, how does a no ground plane antenna work?A no ground plane CB Antenna is a CB antenna that doesn’t require a ground plane (large metal surface under it) to operate. Ground Plane antennas are specially designed to work on fiberglass vehicles and boats. A no ground plane antenna is designed to use the ground or water to transmit horizontally.Furthermore, does a 1/2 wave antenna need a ground plane? Using an antenna tuned for an 800 MHz system (about 3 inches, 7 cm, in length) in the same situation would result in less than optimum pickup. A 1/2-wave antenna does not require a ground plane, making it suitable for remote mounting in any location. Then, does a 1/4 wave antenna need a ground plane? Answer: Yes. All 1/4 wave antennas work best if they are installed in the center of a metal ground plane with at least 1/4 wave length radius (1/2 wave length diameter: ~6 inches for 900Mhz and ~3 inches for 2.4Ghz); larger is better. The antenna should be perpendicular to the ground plane (pointing straight up).Does a CB antenna have to be grounded? Ground Your Antenna Mount If 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.
