IE: a dipole is a complete antenna, and requires no ground for proper operation at the antenna, or at the shack. You don't need an RF ground at all. Your dipole is not the dipole but the monopole with the one radial. A monopole with one opposite radial is a dipole. :/ In the case of a vertical, the RF ground should be under the antenna if a monopole. IE: ground radials under a ground mount, or elevated radials for a ground plane. Your dipole is a horizontal monopole with the one radial. No, it's a dipole. The vertical monopole can have only one radial. I suspect that statement is going to be quite a shock to the hundreds of stations that lay out 120 or more of them. More radials is necessary for a strong stations. To equal a certain level of ground loss, over a given amount of ground conductivity, the number of radials required under a monopole will depend on it's height above ground in wavelength. Do you understand? Probably, when I'm under the clinical supervision of a doktor. :/ The only difference between your monopole and your vertical antenna is the direction. Do you agree? No, because you are mislabeling a dog, and trying to compare it to a cat. In free space, the only difference between a vertical dipole, and a horizontal dipole is direction. |
