Is this guy the ghost of Allen Funt? He has set up such an improbable
situation with his nonsense that we are unable to grasp it, so we suspend
disbelief.

Try to grasp that:

The Marconi antenna is vertical. It consists of an antena and the
counterpoise. The counterpoise can be in form of the vertical wire. So such
monopole is vertical.

The "dipole" antenna with the coax and without the balun is exactly like te
above set.
The only difference is that the second set is horizontal.
Too difficult?

Apparently too difficult for you!

Am I one of what?

If you mean what are MY qualifications to call you a babbling idiot, I
have
been building and using antennas for about 50 years and have a degree in
Electrical and Electronic Engineering.

How long have you been building and using antennas and what degrees do
you have?

Instead writting the "babbling idiot" write a long article on antennas
without ground.

You wrote: "Only end fed monopoles need radials". Do you mean that "Only end
fed monopoles need ground"?

When you have a vertical 1/4 wavelength antenna with a vertical 1/4
wavelength "counterpoise" below it, you don't have a monopole, you
have a dipole.

The "dipole" antenna with the coax and without the balun is exactly like the
above set.
The only difference is that the second set is horizontal.

It can be horizontal or vertical or anywhere in between.

Too difficult?

Too difficult for you.

That is not a correct way to feed a dipole!
There must be a balun between the coax and the dipole.

The balun only improve the monopole . The only one leg is red
(radiate):

The color someone used in an illustrative diagram has no significance
in the operation of the antenna.

Both the halves of the dipole are involved in the radiation.

If it is feed by the two wires transmission line:

Did you notice there is no connection to ground required?

It is obvious that "the antenna with the two legs where the one leg is
connected to the shield of a coax" is the Marconi antenna.
It is not the dipole antenna.

The rest of your antennas (small power) can have the ground from AC supply
or chassis.

When you have a vertical 1/4 wavelength antenna with a vertical 1/4

The real dipole need the ladder line (the two wires).
The coax shield is connected to the ground.
You should write "dipole". In NASA their dipole and your"dipole" are the
quite different things.

It can be horizontal or vertical or anywhere in between.

So you grasp it.

No.
You can use a coax and a balun.

The coax shield is connected to the ground.

Why?

What do you mean with "In NASA"?

I do. But you don't seem to.

Jimp has read modern literature and is correct while Marconi was wrong.

No, it is not "obvious", it is nonsense to call a dipole a Marconi antenna.

A Marconi antenna by definition is an end fed monopole one quarter wavelength
high.

It is not the dipole antenna.

A dipole most certainly IS a dipole.

The rest of your antennas (small power) can have the ground from AC supply
or chassis.

Babbling nonsense.

You are an ignorant, ineducable idiot.
