The "ground plane antenna" is also the monopole:
"To function as a ground plane, the conducting surface must be at least a
quarter of the wavelength (?/4) of the radio waves in size. In lower
frequency antennas, such as the mast radiators used for broadcast
antennas,
the Earth itself (or a body of water such as a salt marsh or ocean) is
used
as a ground plane. For higher frequency antennas, in the VHF or UHF
range,
the ground plane can be smaller, and metal disks, screens or wires are
used
as ground planes".

Note that it does not say that it is sufficient to connect one side
of the antenna to the ground with a wire.

Note what Marconi did: "Marconi, who discovered if he attached one terminal
of his transmitter to a
wire suspended in the air and the other to the Earth, he could transmit for
longer distances."

Irrelevant to anything said, but you are too ignorant to understand why.


A ground plane is something different than a wire to ground.

The nonactive leg of the popular "dipole" is connected with the braid of a
coax and the mass (chassis) of the transmitter.

Pure babble.

Both legs of a dipole are "active".

Not all dipoles are feed with coax.

Some transmitters have no chassis or metal mass of any kind, a good
example of which would be radiosondes before transistors were invented.

They were build on a non-conductive sheet using point to point wiring
and had no metal mass, no chassis, no ground, and were hung from
balloons.

The braid has many wires. Each of them is the radial.

Pure babbling, nonsense.
