The mechanism of radiation is pretty simple from a quantum
electrodynamic standpoint. Accelerated electrons emit
photons. Some of the photons escape the antenna. The
energy lost by the escaping photons must be replaced
by the source. QED. :-)

Art, if you would replace electrons with photons in
your blast-off theory, you will be closer to the facts.

If it concentrated on
say, a simple parallel circuit, a very simple circuit then the
absolute physics of what is being discussed would be an immense help
in explaining this wave discussion.ARRL states that an antenna is a
simple parallel circuit

Here is my civil response: For this discussion there is little benefit
in using lumped component theory. The standing wave stores energy in
an antenna in a manner similar to energy stored in an inductor and a
capacitor in a resonant component circuit but it is not very useful to
use lumped components when explaining why a standing wave cannot be
used to measure delay in a coil, for example.

Further questions that challenge your (and the ARRL's) simplified
model:

Is the resonant circuit dependent on the capacitance and inductance of
the antenna or its length?

If your answer is "both", (which it is), why does it happen to be
both?

Why does 1/4WL of the length of the antenna just happen to be a
resonant point of the capacitance (in x _farads) and inductance (in y-
henries) of the antenna?

Why physically is that so? Nature is telling you something there.

You should understand that concept well before you get to the
radiation of particles (and they WILL be photons).

but this concentration on antenna workings is



blind siding every body as well as providing a means for twisting the
discussion because the makings of radiation is not known.
Why not illustrate waves in a simple parallel circuit so that
observers can partake in this discussion which, if it ever comes to
closure, could then be used to demonstrate their effect on radiation?
Onlookers are more than willing to partake in the discussion but
presently they are on the side lines because as presented it is
limited to only those whose intent is to argue without obtaining
closure and their feeding habits are insatiable as you are finding
out.

Your whole posting is just silly. First you accuse me of lieing now
you want to provoke me with stupidity. You need to upgrade to a
understanding of a tank circuit.Yes, it is used in your transmitter.
Google it and study it. Free speech is great but it also reveals your
mentality. And you are just bull shiting in the absence of knoweledge.
