Sorry, electrons cannot move fast enough to support RF current which cannot
flow inside a wire. The RF EM wave flow is supported by photons moving at
the speed of light in a cloud surrounding the wire.


Photons are the energy portions. Like the tons in sound.

Does it means that the electrons jump off from the end of the radiator?


Electrons are known to "jump off from the end of the radiator". It's called
corona and it is visible at night. Fortunately, it happens only under
special conditions because that energy is not coherently radiated, i.e. not
useful for anything except melting the ends of an antenna.


Before melting the end is lighting. Before shine it is hot. In the all
stadiums the electrons jump off (from transmitting antennas).

In Faraday time no such meters but Faraday had know that electrons
(nuclei)
jump off from the end of the open circuit.


Yes, arcing is a common occurrence. Unfortunately, nowadays it is useless
(and illegal) for RF communications. BTW, nuclei is plural for nucleus and
there are no electrons in the nucleus.


In Faraday time no nucleus. Now the Faradays nuclei have name electrons.
Maxwell name is "electric particles".
All of them are in space. The last names are "Dirac electron sea" and the
"rare plasma".
