What is no ground plane antenna?
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 installed on a vehicle or boat constructed of metal will not operate correctly.
Do mobile CB antennas need 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.
What happens if you don’t ground an antenna?
During a Thunderstorm, anything conductive that is not grounded, will collect a static charge… as the charge builds up, it’ll attract lightning to it. So grounding the antenna, drains off any charge that might build up attracting a strike.
How do you ground a mobile antenna?
(1) GROUNDING ANTENNA: Obtaining a good ground is very important to any HF mobile installation. No matter where your antenna is mounted, it is highly recommended you run a heavy copper strap or braid (1″ to 3″) between the body and frame of your vehicle.
Does ground plane affect reception?
It is worth noting that a poor ground plane or radiating surface may not affect radio reception. You may still receive transmissions from other radios with or without a ground plane. Basically, you can receive transmissions on a clothes hanger!
Why do some antennas need a ground plane?
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 to be used as a reflecting surface for radio waves.
Is it necessary to ground an antenna?
Yes, all outdoor TV antennas should be grounded. Even if you have a newer plastic antenna, there is metal inside. Furthermore, TV signals are made of electricity. The antenna is essentially designed to capture that electricity.
How important is it to ground an antenna?
Grounding will eliminate static electricity, as well as protect against energy to the mast if the antenna comes in contact with live electrical wires. Outdoor masts should be grounded with Grounding Conductors (see F in diagram) to the building’s Power Service Grounding Electrode System (see E) at a permitted location.
Does a ghost antenna need a ground plane?
This is not 1/2 wave which means it needs a proper metal ground plane to work well. It is 5/8 wave length. At that wave length and at 462 mhz you need at least a 12-14 inch metal ground plane for proper distance. Distance will be greatly reduced if mounted on anything other than a good metal surface like a roof.
Does a whip antenna need a ground plane?
An advantage is that because it acts as a dipole it doesn’t need a ground plane.
Why do antennas need to be grounded?
Does a magnet mount antenna need to be grounded?
Mag mounts don’t require an RF ground to the vehicle to work.
Does a car aerial need to be earthed?
Your antenna mount needs to be properly grounded for your antenna to function correctly. Without a solid ground, you’re bound to get high SWR levels and extremely poor performance.
