The problem with you is that you will not take the correct answer
to that question, but you will keep asking it until someone incorrectly
answers that Marconi was right.

Ian did it. He wrote:
"The "static to earth" in my HF aerial is merely to get the static to
bypass
my receiver. The earth connection is not necessary in order to receive
signals."

Tell as if a practical radio exists where the instruments are not
connected to earth/chassis."
I am not asking for what: to bypass or to receive/transmit.

Hello Szczepan
No, I did not say that Marconi was correct. I did say that the earth
connection is not necessary in order to receive signals. I suspect that your
English is not as good as we think.

This is definitely something that I will not be doing. A dipole has low
impedance at the feed point and high impedance at its ends.

A dipole with one ene earthed becomes a monopole.
Hertz transmitter is a dipole. The Tesla's is a monopole.
Todays dipoles are simply the two monopoles.
Thanks this the waves are polarized.

Hello again Szczepan .
You used the term "dobled". Was it a typing error on your part?
Are we discussing spark transmission and non-resonant aerials?

Regards, Ian.

You are just too stupid to understand what it is that Ian wrote.

Meaningless gibberish.

More meaningless gibberish.



Hello folks.

I have a suspicion that Szczepan's English is either not as good as it
appears or that he is using a web translation page.

Szczepan - do you hold an amateur radio licence, please?

I have even never seen a transmitter.
For me it is a "black box".

I only want to know if the box is connected to the earth/chassis.

Your the first answer was Yes ("The "static to earth" in my HF aerial is
merely to get the static to bypass my receiver).

Yes.

Are we discussing spark transmission and non-resonant aerials?

The earth/chassis and the field electron emission..

The point that you are missing is that the earth connection has NOTHING
to do with transmitting or receiving a signal. If is merely there for
safety in the event of a lightening strike or build up or static.

So the radio have the earth/chassis.

Ian's equipment will work no differently is the earth connection is
disconnected. Marconi was WRONG!!!!

And what about your equipment?
Is the earth connection disconnected?

Hey Szczepan,

Spark transmitters are not used anymore.
Try to find some more recent articles about transmitting.

Today we use nicely synthesized carrier waves that are fed to
antennas suitable for the frequency in use, not a noise generator
and transformer to high voltages connected to a random wire net.

Especially when that frequency is somewhat higher (much higer
than what Marconi and Tesla were transmitting on), there is no
need for en earth connection or even a chassis.
That is because an antenna is used that is balanced or has its
own counterpoise for the driven element.

A connection to earth would not be effective anyway, because
antennas used at higher frequencies are often several wavelengths
above the earth, and a wire used to connect to the earth would
not behave like a conductor at those frequencies.

We also operate our antennas well below the point where arcing
occurs, so we don't have to deal with electron emission.

So now please go off to a group that operates the century old
techniques that you seem to be discussing.
Maybe you can find a Tesla coil enthousiasts group where your
voice will be appreciated, although I think they are not using
sparkgaps anymore either.

That his English is horrible is a given, but since he has been doing
exactly the same thing for years now it should be a lot better than
it is.

He has been posting the same idiotic crap for years to the sci. groups
and getting the same responses.

He is incapable of comprehending that Tesla, Maxwell, Marconi, etc. did
NOT have a full understanding of RF over a hundred years ago.

He keeps posting the same idiotic questions, with references to century
old quotes, over and over no matter how many times he is answered.

Szczepan - do you hold an amateur radio licence, please?

No, he does not.

Hello Szczepan.
It seems that you totally misunderstood my answer.
A ground connection is NOT necessary in order to receive a signal.

You tell me that you have not seen a transmitter and regard it as a black
box. I recommend that you get a modern textbook on radio technology so that
you can understand how radios and aerials work.

Kindest regards, Ian.
