Tell us which is which. Without your usual nonsense.


The red one: http://en.wikipedia.org/wiki/File:Dipolefeedrad.png

I know I'm asking the impossible here, but maybe just this once you could
answer a question clearly and directly.


I assume that Joel dipole is feed with a coax. Because: "Many people have
had success in feeding a dipole directly with a coaxial cable feed rather
than a ladder-line. "


What is a "Joel dipole"?

Is it the Joel case?

Do you agree that such "dipole" is the monopole?

No, you are an idiot.

The antenna type is NOT determined by the feedline.

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?

An outright lie.

If you were here to learn, you would not be arguing with people who have
spent decades building and using antennas in the real world, people
ranging
in education from knowledgable hobbyiests to degreed engineers and
scientists.


All the links I quote are wrote by "people who have

Are you one of them?

Not "if", moron, always.

READ your own link.

If a dipole is fed with coax AND if there is NO balun device, then common
mode current flows on the outside of the coax and the coax ALSO radiates.

If a dipole is fed with coax AND if there IS a balun device, then there
is no feedline radiation.

In either case, the dipole radiates from both halves.

That is what your link says happens but you are too stupid to read it and
can only look at the pictures and misinterpret what they mean.

That may be true, however you appear to be too stupid to understand any of
them and just misinterpret the pictures.

Your latest babbling nonsense about the page at:
http://www.deltadx.net/ABCDx/Sections/Antennas.htm

proves you just look at the pictures and either don't read or don't understand
the text.

Are you one of them?
S*


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?

You truly understand nothing about how feedlines and antennas work. It
is worthless trying to explain them to you because you also refuse to learn.

Again you show you know nothing about antennas or the real world.

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.
