Here is the Tesla's electron gun:

"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:

So we know that the electrons are liberated from the end of antenna.

No, they are not in general.

That is total nonsense.

But where the electrons come from?

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.
