What is a no ground plane antenna?
What is a 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 you need a ground plane to receive?
You may still receive transmissions from other radios with or without a ground plane. Basically, you can receive transmissions on a clothes hanger! It is vital to understand that you must check and set your antenna (tune your antenna) to ensure it is functioning properly.
Does a CB radio need to be grounded?
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 does ground plane independent mean?
Ground independent means that it simulates a ground plane to ensures it performs correctly even if there is minimal to no ground plane. A ground plane is the surface your antenna is affixed to. An independent ground antenna can also help to correct the signal range of your antenna.
Does a mobile ham radio antenna need to be grounded?
(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. (NOTE: Copper wire is not sufficient!)
Why do you need a ground plane?
In digital and radio frequency PCBs, the major reason for using large ground planes is to reduce electrical noise and interference through ground loops and to prevent crosstalk between adjacent circuit traces.
Does a receiving antenna need a ground plane?
The Purpose of the Ground Plane For example, mounting an antenna that does not require a ground plane onto a big chunk of metal can adversely affect performance. The ground plane, if not needed, will certainly distort the antenna pattern. It may also add loss and detune the antenna.
Do you need an antenna for a UHF?
All UHF radios transmit best on a line of sight basis, which means that it’s important to position an antenna in such a way as to provide maximum coverage.
