Thread: Why Antennas Have Ground Plane?

  1. #11
    Basically, "Ground plane" is an old denomination. I think radials is more appropriated.
    As abcd567 said, radials are part of the antenna, half side of the antenna.
    In the 1/4 vertical model, radials are affecting to impedance and to the lobules.
    In a 1/4 vertical, 50 OHm are achieved with radials around 45º.

    Nothing wrong about the use of the term ground plane and I don't know why you suggest that it is in some way an old term, radials are merely the means by which that effect is obtained. 'Radials' by itself has no meaning.

    I said that because talking about ground someone could be confused with ground reflections, or ground gain, or any other ground effect.
    Those affects, as you know, are happening to any terrestrial antenna.

    There is more likelihood that people will be confused by your ideas than are helped. This is a forum for aircraft tracking enthusiasts that in most cases have limited radio theory knowledge.

    I agree that.
