Here is the Tesla's electron gun:
http://en.wikipedia.org/wiki/File:Sp_xmtr.png

"In April 1887, Tesla began investigating what would later be called X-rays
" We now know that this device operated by emitting electrons from the
single electrode through a combination of field electron emission and
thermionic emission. Once liberated, electrons are strongly repelled by the
high electric field near the electrode during negative voltage peaks from
the oscillating HV output of the Tesla Coil, generating X rays as they
collide with the glass envelope. " From:
http://en.wikipedia.org/?title=Nikola_Tesla

So we know that the electrons are liberated from the end of antenna.
But where the electrons come from?
From: "the earth"?

No, they are not in general.

That is total nonsense.

They don't come from anywhere because it is not happening.

You are confusing the specific operation of a Tesla coil with radio in
general.

You are a babbling idiot.

So I suppose we should develop some antennas that have a current maximum at
the end of the antenna?

I wworked for 6 momths for a company that manufactured thin-film optical
filters.

The glass pieces were placed ina vacuum chamber. along with the
crucible(s) with the coating material(s).

Once the chamber was evacuated an electron beam was used to heat the
coating materials, which usually sublimed and were directed magneticaly
to the glass.

I still have one of the electron guns (filament burned out). It looks
like an oversized tube with an open ended glass tube on one side where
the beam was directed out.

So "we" know from you that todays antennas do not liberate even one
electron.

Antennas liberate the EM waves and the electrons as a by product.
Do you support this?

Antennas liberated the EM waves and the electrons.
More electrons is liberated more electrons is flowing in the antenna.

EM travel in space. Electrons fall down on the earth.
For this reason the earth is necessary.
Do you agree?

No. There is a current minimum at the end of an antenna because there is no
place for electrons to flow.

All who know what the "field electron emission" is.

"Introduction.-The main features of t h e phenomenon of the
extraction
of ele&ons from cold metals b y intense electric fields are well
known,"
From:
http://www-project.slac.stanford.edu...ces/fowler.pdf

Each metal with the excess of electrons liberate them.
A transmitter antena liberates radio waves, heat and electrons.

Waves travel in space, heat is dissipated and electrons are taken from the
earth.

This is a bunch of babbling, rambling, meaningless, gibberish.
