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, I believe you are correct that what is known as basic physics
does not have universal consensus in this group which is not all that
bad because we are all amateurs.I know that mass is not constant in
itself since it is always self adjusting to maintain equilibrium. It
would also appear that what is emitted is so small and numourous that
it can be seen as a cloud or a field.
I also believe there is some sort of consensus that these two clouds
are still somewhat homogenous after they have escaped from the initial
gravitational forcesi.e merging of these entities is achieved beyond
the arbitary border.
Some have gone off at a tangent by introducing 377 ohms as a ratio
which ofcourse is an impossibility which destoys the credability of
their whole statement. At the back of my mind I was trying to
determine how the makeup of skin depth occurs since at a moment in
time the surface of the conductor is seen as composed entirely of
static particles and what changes occur when the material conducts
since the surface is totally boundduring the radiation process. So Tom
this is a good time to bow out, since once again on this group we have
encountered a situation where actual knoweledge is piece meal at best
and where continuation could only introduce falacies to the subject.
One thing I am assured of is that despite claims offered this is by no
means BASIC physics theory but a collection of fragmentary knoweledge
which could easily evolve in what is termed junk science as the many
opinions merge.
Gentlemen have a great day and try to concentrate on the beginnings
that Gauss has now provided us by the addition of the metric of time
and formulate a theory within that context since it presents an avenue
of new additional information.than that previously known.

For those who are interested in the finite details of radiation I just
read in a industrial magazine that it has been determined that the
electric field in the near zone is transformed into a electric field
of an opposite polarity in the far zone.
This by implication upsets the idea that surrounds radiation emmission
from the far zone if there is still in existence an electric field.
Thus it would appear that basic physics has still not determined the
inter relative actions from a dormant static field to a mobile
radiative field. Note that the introduction of the word of ' polarity'
into the subject of antennas is not unusual in the antenna
industry.i.e. it is their words not mine.
