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:
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"?

Who is "we"?

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:

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.
