One suggestion is that you talk with some technically competent people in
Poland and describe your definition of dipoles.

Most likely, they will not agree with your definition.

As you see in Poland and "here" are the technically UNcompetent
people.

Do you see the difference between the Hertz dipole and the
radioamateur dipole?

Yet more babbling nonsense with no understanding of the text you have
quoted.

You are an ignorant, babbling, ineducable idiot who knows absolutely
NOTHING about antennas or how they work.

You don't even understand what an antenna is or the difference between
an electric field, a magnetic field, and an electromagnetic field.

How many antennas have you built in your lifetime?

Why do you refuse to answer the question?

Is it because you have built zero antennas and you are trying to say all
the people that have successfully built hundreds that they are all wrong
and you don't want to admit you are an ignorant, inducable, idiot?

Why can't you obtain and read a university level textbook on electromagntics
in any language?

Is it because you are too stupid to be able to understand the material?

As a normal in the all country is leakage. Corona is from time to time.

"Physics, Electricity . the loss of all or part of a useful agent, as of
the electric current that flows through an insulator"

In overhead power supply the air is an insulator.

The both (corona and leakage) are nonsymmetric in AC.
So the ground is the only remedy.

Hello Szczepan.
Neither you nor I would want to be near any "leaky" insulator.

Air is the "leaky" insulator.
I was many times under the 400kV line and I am still alive.
Is it dangerous in UK.

Irrelevant, babbling, nonsense.

You probably do not know the difference leakage/breakdown.

You do not know anything.

You appear
not to understand the definition and meaning of "insulator". Your past
behaviour indicates that there is no point in trying to explain it to you.
All I will suggest is that you try to acquire and read a textbook on the
subject.

Textbooks are for children.

You don't even understand what an antenna is or the difference between
an electric field, a magnetic field, and an electromagnetic field.

That fields and the gravity are only in the textbooks (as e sperate
chapters).
They are also in engineering.
In physics is only one field.
Do you thing that in space are the seperate mechanismus?

Do not write that the charge at rest create the electric field and if it
travel it create magnetic field.

The antennas work according to physics law.


Why can't you obtain and read a university level textbook on
electromagntics
in any language?

Electromagnetism was the hipothese proposed by Maxwell. But Royal Society
discarded it.
Have sense read it?

Not to be a smart ass but weren't a lot of the old British cars
equipped with a positive ground? What's up with that?

The electrons come out of the negative end of the battery. The Old Brits
were smart. They didn't want the electrons to jump off of the ends of
the cars, so they tied the positive ends of the batteries to the car
chassis. Except for those cars they exported to Poland ;-) .

I think it had something to do with the cars driving on the left side
of the road...

Either that, or it rains so much in the UK the electrons that would
normally jump up are washed down by all that water so you have to put
the negative side up to capture the electrons...

The fun part of owning one of those cars was watching panic on someone's
face when you got a jump start and hooked the jumper cables up backwards.
