And another side benefit. This NG has had few postings in several
months. I haven't seen this much activity on r.r.a.a since the GFW.*

You and others are correct. The MIQ has injected some fun.

Nope, you just don't understand what is meant.


In the days of wired electronics, the chassis was the metal box the
equipment
was built in and used as a common return, i.e. what is called ground but
has no relationship to the Earth. By convention it was mearly the common
connection point for the most negative voltage.

In todays world of circuit boards, there is often no chassis.

Most portable equipment these days is a circuit board in a plastic box.


"This is usually a

No chassis.

No ground, as in to the Earth, connection.


The "large conductor" works as the earth.

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

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

You finally agree, but for all the wrong reasons. :|
Reboot and try again. Like Will Robinson, you are still
lost in space.
I'm not even going to try to explain why, as you likely won't
believe a word I say.

I believe in each your word. But I simply do not know where in your
equipment the "large conductor" is.
Probably it is the coax: "Many conventional coaxial cables use braided
copper wire forming the shield".

I also belive in each Tesla's word. He discovered that in his secondary coil
is the oscillatory electron flow from the earth into the air.
Why is it impossible?

In your statements, you never specify what a "large conductor" is.
Today, transmitters are often very small and still they work OK without
any earth connection.
How large should a "large conductor" be?

Probably it is the coax: "Many conventional coaxial cables use braided
copper wire forming the shield".


The transmitted signal flows only along the inside of the shield of the
coax. The outside is supposed to carry no signal. If it does, there is
a problem with the antenna system.

I also belive in each Tesla's word. He discovered that in his secondary coil
is the oscillatory electron flow from the earth into the air.

We do not operate our transmitters in the region where electrons start
flowing into the air, because we do not like arcing. Tesla did, but he
was in a different business.

Because RF EM waves are not made up of electrons. The particles that
are flowing in an RF EM wave are photons. RF waves travel at the speed
of light. Electrons cannot travel at the speed of light. If Tesla
actually believed that an RF wave consists of electron flow, he was
simply ignorant of quantum electrodynamics. That may be the reason why
he failed to transfer large amounts of power through the air in an
efficient manner.

Electron waves travel. Electrons have different speeds like the all gases.

He wrote that for this you must use the higher frequency than was possible
in his time.
Now all transfer large amounts of power through the air in an efficient
manner.
Light is an example. But now we have the free electron laser.
