Ahhh come on guys, and Art, , get a grip...

Electrons are 'emitted' from the surface of a conductor only under
specific circumstances, such as the Photoelectric Effect, in a direct
electric arc such as an arc welder, off the hot surface of a
filament, off the cathode of an electroplating device, etc.... All of
these are mass events where the departing electrons will in time
change/erode the surface material of the emitter...


Electrons do not normally depart the surface of an RF antenna; local
corona discharge, or mechanical short circuit, or electric arc, being
the main exceptions and are not germain to the intended purpose of
the RF antenna..
The antenna surface is not eroded or mass altered by the long term
emission of electromagetic waves because no electrons are being
launched/emitted off the surface res ipsa loquitor...

OK, now back to the regularily scheduled reruns of Howdy Doody you
can learn a lot from these
