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 denny / k8do |
