A real well in soil will be the perfect infinite source of electrons.

A source of electrons is not required. Transmitters use AC (alternating
current) so there is no net flow of electrons.


AC is in a transformer.
In an antenna is the oscillatory flow of electrons. So there is the net
flow of electrons.

"It is now known that this device operated by emitting electrons from the
single electrode through a combination of field electron emission and
thermionic emission.[citation needed] 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"

Do not you know that?

If that were true, there would be a DC current into a transmitting antenna
fed only by HF (AC) current.
But of course there is no such DC current. If it were there, it would
mean there is nonlinearity in the antenna and there would be severe
intermodulation.


Always is the "DC" (net electron flow) from the counterpoise to end of an
antenna.
