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
large conductor attached to one side of the power supply (such as the
"ground plane" on a printed circuit board) "

No chassis.

No ground, as in to the Earth, connection.

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.

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?

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.

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.

Adequate to electron emission.

Electron do not start.
Electrons are flowing into the air (and vacuum) at each voltage.
The thin wire is the best "cold cathode".

Transmitters do not emit electrons. They emit electromagnetic waves.
You only see electric current in the feed to the antenna, not externally.
When the antenna is not driven relative to earth, this is not causing
current into the earth, and so no connection to earth is required.

But in my cellphone, the coax feeding the antenna is maybe only 1cm
long, or even shorter. How can you call it a "large conductor"?

What current do you measure in a wire connected to your 12v car
battery, and hanging freely into the air?
This is the current caused by your electrons flowing into the air.

In this case what is being discussed is electrical safety, not radio.

Portable radios do not have a "large conductor".

Gibberish.

Usually aluminum tubing or copper wire for fixed antennas and usually
chrome plated steel for portable antennas.

Antennas do not have a chassis.

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.
