In direct terms I have stated that current flows down the

of a radiator if it is of a fractional wave length.

OK, you must be talking about an AC current as there is a wavelength
involved. But if you are implying there is current in the center matching
the amplitude of the current on the surface you are wrong.

See this link
http://en.wikipedia.org/wiki/Skin_depth

Note the phrase regarding current;"the magnitude of which is greatest at the
conductor's surface". This is where the current is.

There is also this statement "the current can be flowing in the opposite
direction to that at the surface." Note that there are qualifications on
that statement (on the page referenced).

So, while there can be some current flowing inside the conductor, it does
not say it is a matching current in the other direction. By saying most of
the current is at the surface, it conflicts with your statement.



A very simple
statement which nobody wishes to address.

You are trying to apply "For a force there is always an equal and opposite
reaction: or the forces of two bodies on each other are always equal and
are directed in opposite directions."
(from "http://en.wikipedia.org/wiki/Newton%27s_laws_of_motion" )

You make a simple statement, brought about but applying a concept
incorrectly. I don't think Newton said anything about electricity and flow
in conductors. Newton's law doesn't say what the opposing force is, so I
don't think you can say it is anything specific.

I would
prefer however the discussion to at least start with equilibrium which
leads to why or why not it is correct that current can flow thru the
center of a conductor the answer of which is not in the books.

The right books would tell you that AC current does not flow in the center
of a conductor.

As others have stated, you need to clearly define what _you_ mean by
equilibrium.

Some
people prefer to read the last page of the book first.
I prefere to examine foundations before determining the merits of a
house.

Those foundations need to take into account all the considerations, not just
the ones you know or want to talk about. You may have read some of the
book, but you skipped quite a few chapters.

Consider your statement to have been addressed.

You will note that both links include some math. This is something you don't
provide with your explanations. If you went through the rigor to work out
the math and present it to the group with sufficient clarity you might get
someone to believe you. If you want someone to believe you, it is up to you
to effectively communicate your ideas.

It is hard to tell if you have a useful concept regarding antennas, are
completely lost, or just a troll.

But, just in case you have something, then...

Many antennas are built using tubing for light weight. So, if there is a
current flowing in the middle, it is good that the ends of the tubes are
crimped, or plugged. I wouldn't want the flowing electrons spilling out
onto my lawn.
