# The radial connected with the shield of the coax is the ground.


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

The true horizontal dipole (electrically symmetric) radiate in one
direction
only. A monopole in all directions.

So a half wave wire broken at the center is a monopole with a single
radial if it is fed directly with coax?

# Yes. The one leg is the radiator and the second is a ground (like a
# satellite chassis).

So with direct coax connection, one leg radiates and the other leg is
ground?

Yes.

Would you be willing to touch the end of the "ground"/"radial" wire while
transmitting?

The electron density changes periodically in the both legs (while
transmitting).
Are the voltages equal in the both legs?

But the question was: if the half of the antenna connected to the coax is
ground, would you be willing to touch the end of that half while RF power is
supplied to the center conductor connected half of the antenna?

That would be a good way of verifying your theory.

It is not my theory. Somebody wrote:
"H. Horizontal, unbalanced antennas, such as a long wire or random wire,
need an RF Ground wire that should be 10-15% longer than the antenna wire
itself. This is often called a counterpoise. The RF ground wire in this case
can be laid out in many ways, just so long as it does not cross over itself
to form a loop. Indoors, such wires are often run under carpets or along
walls, out of windows, or anywhere else convenient. This wire will often
have large RF voltages on it, so it should be kept away from people or
insulated to prevent contact." From:
http://www.sgcworld.com/radialstechnote.html

Your "dipoles" are "horizontal, unbalanced antennas". The radial or
counterpoise "should be kept away from people or insulated to prevent
contact."
The "mechanically symmetric dipole" is the simplest solution.
Do you agree?

It appears that your reference above from SGC contradicts your single radial
assertion.

For a half wave antenna broken in the center, you claim that the half
connected to the coax braid is a radial.
If it is a radial, why does it have high voltage at the end, behaving like a
dipole?

""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".

Each transmittel as a source of AC produces the high voltage at the both
ends.
If the one end is in the soil you have the monopooe antenna.

But next Marconi discovered that the radials are better than the soil.

You should understand that 120 radials have lower voltage than one radiator.
Also one radial from your "dipole" connetced in series with the shield has
lower voltage.

Have you posibility to measure the VSWR on the both legs your "dipole"?

For certain types of antennas.

Most of the antennas that exist today did not exist in Marconi'e lifetime.

Both ends of what?

Maybe.

But next Marconi discovered that the radials are better than the soil.

Only under certain conditions.

Babbling nonsense.

Babbling nonsense.

This is an idiotic question that shows you haven't the slightest clue
how antennas work.

Actually, some of the amusing babbling nonsense does occasionally have a
small grain of sense. And even if it obviously IS nonsense, can we
always say precisely why it is?

If a dipole is fed directly with coax, is the power (voltage and
current) into each leg the same? If not, why not?

Again, if a dipole is fed directly with coax, and if you could insert an
SWR meter at the feed into each leg, would the two readings be the same.
If not, why not?

If you actually knew anything about antennas you would realize that is
an immensely stupid question.

If you are really interested in electric waves look at Maconi Nobel lectu
http://www.nobelprize.org/nobel_priz...ni-lecture.pdf

Most of the knowledge of electromagnetic waves, not "electric waves", was
obtained after 1909.

Your are not only and idiot, you are an idiot 100 years out of date.
