The "large conductor" works as the earth.
S*

So you agree that a transmitter needs no connection to the earth?

Of course YES. The "large conductor" is enough.


There is no "large conductor" on many modern circuit boards so you are
wrong yet again.


Hello jimp.

Pity he can't define "large" or understand "ground".

It has no conventional meaning.

He probably found the phrase in some speculative writtings of someone who
has been dead for at least 100 years.

Thanks for that info. I was starting to wonder if I'd missed something.

Electron waves travel.

No doubt, and please give an example of an electron wave. One more
time. It is impossible for electrons to travel at the speed of light.
But RF EM waves travel at the speed of light. Therefore, it is
impossible for RF waves to consist of electrons. Electrons act as a
bucket brigade for "buckets" of photons.

And what about the "displacement current?

If Maxwell had known about photons, he would never have invented
displacement current.

Assume we have an ideal transmission line terminated in an ideal
capacitor with two plates. It's easy to prove that the displacement
current flowing from one plate back up the transmission line, through
the source, back down the transmission line onto the other capacitor
plate has to be traveling much faster than the speed of light. Does
that give anyone pause to question the very existence of "displacement
current" in reality?

Back when physicists and engineers were ignorant of the existence of
photons, that was the best they could do to explain electromagnetic
fields surrounding free electrons being energized by AC signals.
Nowadays, we know that at RF, the electrons oscillate virtually in
place and it is the photons that are responsible for energy transfer
(flow).

Probably not in ham radio but a single electron exhibits the same wave
behavior as a photon in double-slit experiments, i.e. a single
electron seems to go through both slits and interfere with itself on
the other side. That is wave behavior. Strangely enough, a single very
large Buckyball exhibits similar wave behavior.

While I do not disagree with what you said, note the 's' in "Electron waves".

A particle may have some wave properties but that does not make it a wave.

Each of them is in small fixed box and oscillate?

and it is the photons that are responsible for energy transfer
(flow).

Each waves transport mass and energy. The oscillations are not simmetrical.

You are a babbling idiot.
