They do not flow from the transmitter to the end of antenna. They kick
the
next ones. It is the oscillatory flow.

You have been told time and time again that there is no corona in normal
antenna operation.

But is in unnormal operation. When it is seen?


Only when you output kilowatts of power and there is some point in
the antenna where the voltage is very high.


I was asking on the speed of electrons in the conductor.


No you were telling that electrons were jumping off the antenna because
of corona, which is nonsense when the transmitter is low power, and
points to an operational problem when the transmitter is high power.

But a radio amateur knows that it is possible to transmit signals with
arbitrarily low power and that the range becomes smaller but it still
works all the time. So even with very low voltages, where there is
no corona, a transmitter still transmits.


"Leakage current is also any current that flows when the ideal current is
zero".

Real current is not the ideal one.


The average Pole may not be stupid, but that does not mean there don't
exist very stupid Poles.
