If it were true, an antenna

don't see that happen on a well-designed antenna (it *does* happen when
there are bad contacts with diode-effect in the antenna), we know that
an antenna by itself cannot be nonlinear and so there cannot be a net
flow of electrons.

The net flow of electrons is from the counterpoise to end of antenna.

How do you explain that there is no intermodulation as a result of
the nonlinearity of the antenna that you claim?

I am here to learn.

No, you are obviously not here to learn.

No matter what you are told from people who have actually been dealing
with antenna systems from years, your response continues to be babbling
nonsense and quotes from century old literature that has long ago proven
to be false.

Lately I have learn from Bilou:
"In such cases it is convenient to put the things to their limits.
Imagine the diameter of one half is infinite.
You now have a quarter wave over a ground plane.A well known case."

Babble.

It means that a dipole fed from a coax is the monopole (a quarter wave) with
the counterpoise.

No, it doesn not mean that.

"In the case of very rocky or poorly conducting soil a counterpoise often is
substituted for a buried network of wires. A counterpoise is a network of
wires place above the earth a slight distance and insulated from it, so
arranged to produce a very high capacity to the earth."

This is just a random factoid dealing with a particular situation for
a particular antenna type and NOT true in general.

So I know now why you all claim that a dipole do not need a ground.

No, you do not know anything.

A dipole does NOT need a ground.

The number of radials is the power dependent. More power radiated more
electrons must be taken from a ground.
Do you agree?

No, this is babbling nonsense.

Radials are only required for an end fed monopole.

The number of radial required is dependant on the ground conductivity and
totally independant of power.
