Is the field electron emission from the tip top of antenna or not?

Yes it is, but the effect being talked about is corona discharge, and
has nothing to do with the wanted radiation of radio waves. It is an
*unwanted* effect on normal antennas, and occurs when the voltage at
certain points gets high enough to cause ionization of the air. I repeat
it is normally an *UNWANTED* condition on a normal radio antenna used
for communication.

What happens on antennas is NOT "field electron emission" by the modern
definition of the term.

Corona discharge is something else, related, but something else.
