Default Anyone know where I can find plans for an artificial ground?

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.
