Default Does NEC-2 model wires as solid or hollow?

Art: Whether or not a radiator meets your definition of
"equilibrium," the r-f current flow along it ALWAYS falls to ~zero at
its unterminated end(s). It MUST do so, as no real, physical path to
conduct r-f current.exists beyond such a limit.

The near-total reflection of such current results in the standing wave
patterns seen in the plots linked below.

This link also shows that the reflected current travels along the
outside of the conductor. If it did not, it would NOT result in these
current distributions carefully measured by Gihring and Brown over 70
years ago, and which you continue to spurn.

RF just look at what you have written and I suppose shouted in
response to my post

I gave the reasons for my line of thinking having gone thru the
routine of reading and accepting
what the books say.
You spurned my statement giving no reason why it should not be
accepted
Not surprising really as that is the pattern of this group.
Before that I raised the question that if antenna programs all agreed
on the sloping radiator as being the best is that a reason on which I
can declare programs as proof as what I do.
Yup, no answers either because I was spurned or nobody is familiar
with the programs to supply an answer.
Now you throw at me the books together with some sort of abstract and
demand that I should fall in line with everybody else. Well once apon
a time I was a lemming and believed all that was in print.
Now I am examining everything, point by point for my own satisfaction
and coming up with different solutions. Yes I am well aware of the
books that are thrown at me and now I am thinking for myself
which if anybody is going to progress all must do. For that you object
because apparently your request comes first in your mind. Now look at
what you wrote again in a logical fashion and then retire to the
outhouse and think about the rationalisation of the modes of progress
that I supplied
and you state why some would be rejected and why together why
something totally trumps what I stated or answer the question on
antenna computer programs.
On the other hand if you have a question start a new thread !

Not so, Art.

The simplest reason that you should abandon your line of thinking
about there being no current reflection from the unterminated end
along the outside of all radiators is that such beliefs were proven
invalid by the measured results of Gihring and Brown over 70 years ago
-- as shown in the excerpt of their IRE paper which has been linked to
twice, now.

the more it gets quoted the more he will consider it lemming talk and reject
it. art is in his own little world now, full of magical levitating
diamagnetic neutrinos and burrowing anti-eddy currents up the middle of
conductors... of course, where those currents go when they reach the
feedpoint would be an interesting thing to hear, maybe art can comment on
that for a while... they probably just jump up to the surface again and go
around in circles.

so you can't even come up with another technical comeback? just got to
stoop all the way down to a cheap personal attack. I guess this thread is
over then since you have run out of fun things to say.

Nope
You have the solution in your own hands where you have total control
if you are able to use a antenna computer program.Many on this group
have an aversion to computers and thus rely on other means which puts
control
in book authors. If you have a similar aversion thats O.K.
For those who can use a computer they can determine for themselves if
antenna programs can be trusted or not. The exercise is totally in
their hands where they can manipulate the rules in any way
when using these programs. If it works out that this group cannot cope
with computers then the solution will not surface and thus reliance of
the truth resides some where else and not in their hands.
Simple, simple simple

No,No,Noi There is no evidence that you have a yearning for the
backsides of man
it is just a play on words which point to your error in thinking. ala
the slip. Get it?
I have made no attempt to hide my thinking with a torrent of words
under the guise of shakespeare
to provide cover
I provided a single liner. No more, no less
