Look at "Simplest Crystal Radi" in:
http://hackingwithgum.com/2009/06/08...s-really-work/

There is the antenna, diode and ground. Is there the "pulsatile electron
flow "?

If the transmitter produces the AC current and at the end of the antenna
the
voltage is doubled and the field emission take place is there the
"pulsatile
electron flow "?

In radials no voltage doubling so the field emissions take place only in
one
end.

Is it too dificult for you. You are an engineer.
how does the electron know if it is at the end of an antenna wire or

the end of a radial wire?

The first sensible question.

"Radials and Counterpoises have two basic purposes:
1. To improve the RF ground conductivity for the ground current return path.
Unless you live in a salt-water swamp, your ground conductivity makes a very
poor path for the return of ground currents. This increases the ground
losses and reduces the efficiency of an antenna that needs a good RF ground.

E. More radial wires are generally better. As the number gets larger, they
improve the RF Ground less and less, to the point where there is no
difference when adding one more radial to a system that already has 120
installed. Minimum systems of as few as 4 wires can provide an acceptable
ground and increase the antenna's efficiency by a significant amount.
Generally, 6-8 radials is the minimum that should be used." From:http://www.sgcworld.com/radialstechnote.html

As you see in the radials are many ends. There is the lower voltage and
almost no radiation (electron loss). Radial work like the receiver antena
(caught electrons from air)

Without the radials your stations can work only in a "salt-water swamp".

S*

yes, but how does the electron in a single radial know it is at the
end of a radial and not double as opposed to the electron at the end
of an antenna that does double??
