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?

Marconi wrote that all antennas needs ground.

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

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.

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.
