Well, you must admit we could use something to jumpstart discussions on
this newsgroup.

Maybe SB can explain the difference between a monopole with a single
ungrounded radial, and a dipole.

Each radial, grounded or not (but connected to the shield of the coax), is
the ground.
The Earth, the Moon, a satelite and each piece of conductor is ground for
antennas. Radial is one of them.
Ground must be adequate to kW.

Monopole is not directional.
Dipole is directional.

Wrong.

All gibberish, as usual.

Wrong; a monopole can be directional, all you have to to is tilt it slightly.

What if the single ungrounded quarter wave radial is in line with the
quarter wave radiator?
Is it still a monopole?

Monopole is not directional.

Does this assume the monopole is vertical?
What if it is horizontal? Is it still non-directional?

Dipole is directional.

Of course.

In the space no the directions.
The monopole radiate from the end part of the wire. So the one mast is
enough.
But you can make the two masts.

Of course.
To have the directional antenna you must have the antenna array:
"An antenna array is a group of radiators whose currents are of different
amplitudes and phases. They use electromagnetic wave interference phenomena
to enhance the radiative signal in the desired direction and diminish it in
the non-desired direction". From:
http://en.wikipedia.org/wiki/Antenna...lectromagnetic)

The electrically symmetrical dipole is the antenna array.
The whip antenna is always non-directional. But in mountains it work better
if it is horizontal.

Each antenna made of wire radiate from the end piece of the wire. So the
wertical radiate in the all direction but tangent to the Earht surface.
The horizontal radiate in direction of ionsphere. It is usefull in moutains.

The directional antenna has the lobes.
The monopole antenna shorter than 1/4 wave has no lobes.
But a long wire antenna have lobes. There are the many "poles" (nodes) and
the interference take place.

Wiki may be correct, but your interpretation is nonsense.

The electrically symmetrical dipole is the antenna array.

A dipole is a dipole and is not concidered an array by anyone but you.

if it is horizontal.

Wrong and wrong.

Wrong.

You are still a babbling idiot.

Wow...you gave a lot to digest.

Just to understand the discussion, let's address the monopole with one
radial.

Assuming the monopole is 1/4 wave long, and has a 1/4 wave long radial.
The radial is in line with the monopole. Everything is ungrounded.

How does that configuration of a monopole with one radial differ from a
dipole?

The first dipole was the Hertz dipole. The both legs were fed with the same
frequency but not in phase. The both ends radiate with the same intensity.
The Marconi antenna has only one radiated leg. It is almost in the free
space (masts are high).

The horizontal dipole radiate in one horizontal direction only. The vertical
in all horizontal directions. But the mast must be very high.
The horizontal, vertical or tilted monopole radiate in all directions. Your
cell phone has the monopole.
