Nope, RF electrons don't actually flow. They essentially vibrate in

place.

The same is with the all AC. If between the live line and the ground is the
diode "Electron must flow from the line to the ground".

"For a copper wire of radius 1 mm carrying a steady current of

10 amps, the DC drift velocity is only about 0.24 nanometer per
microsecond." At 10 MHz, the electrons would vibrate back and forth at
about 0.01 nanometer per 0.1 microsecond. Consider how large 0.01
nanometer really is so for all practical purposes, electrons don't
flow at all at HF frequencies. Electrons at HF are just a bucket
brigade for the photons that deliver the RF energy to the diode
detector. Unless a circuit is at DC steady-state, photons are
involved, i.e. RF involves photons which constitute the RF fields and
RF waves.

No matter how big the back and forth are. If is a diode electrons must flow
in one direction.
Do not be lazy and measure it.
S*

I can not debate your particular area other than to point what I have
in actuality.
By removing all reactance especially the magnetic field the current
flow removed itself from the material and travels on the surface.
This is not unusual as superconductors drop to zero resistance when
the magnetic field is canceled or removed. There are only two
resistances in radiation and if no skin depth is then generated then
the material and its resistance is removed from Maxwell's equations
Now one can question my understanding as to what is happening but the
fact is my antenna
swr does not go above 3:1 no matter what band I am on! Yes, by not
understanding what is really happening it would be easy to say "dummy
load " but that is not the real answer.
So I would ask all what exactly is impossible
about the sequence of event that I describe while adding that computer
programs confirm it?
By the way the antenna is sitting om the grass
as height does not affect dish antennas!

Pick a band. Pick a time. Let's have a contact.

I know what the answer will be of course, an excuse why you can't have a
Q with me or anyone else.
