What do you mean by (self) resonant?

Physics shows that NO radiator as small as fits into the rotor on your
tower, by itself, could possibly be self-resonant at "TOP band."

With "David" being barred from the group there should be no obstacle
to closing this thread
It really was all for his benefit so he could provide insults and now
there is no need for it.

Watch the PTO print outs. No statements last for ever in physics
I'm done

You've been done for a looong time, Art. *You just don't realize it yet..

Your patent attempt proves nothing. *It's bad physics, and even with the
clueless dips that work in the patent office you are still being
rejected. *It's gotta be pretty useless if they won't approve it.

It is very normal for them to request changes. Obviously you have
never filed a patent
or done anything that would warrant one. Why not pair up with David
and write one yourself
or do you have some already? No that can't be, otherwise you would be
aware of office actions as it goes on all the time. So is it you who
is now Master of the group and self esteemed expert that we all now
have to follow? Your insults are as good as Davids was!
Either way I'm done for a while.

"David" had nothing to do with the last 4 exchanges anyway. What the
hell are you blabbering about?

And who "barred" him? You? If you think that's the case, you carry no
weight with the group to begin with, and no one, no matter how much
respect they get from the group, can bar anyone.

This is an open newsgroup, and anyone can post, even loonies like you.

Wonderful!! But I doubt you will keep the promise.

And you have no idea of how many patents I've been involved with. But I
can safely say the companies I have worked for have made more money from
our patents than you have.

Which should have been "than you have from yours."

assumption of equal forward and reflected traveling waves of current can't
be right, because that would imply no radiation ...

Of course you are right. But the forward and reflected waves
are equal at the ends of the dipole. At the feedpoint of a
1/2WL dipole the reflected current is only ~10% down from
the forward current so the equal current assumption through
the center loading coil is definitely only an approximation.

The question remains: How can the current on a standing wave
antenna, known to change by only 2-3 degrees in 90 degrees
of antenna, be used to measure the delay through a loading
coil installed in the standing wave antenna?

Incidentally, the equal amplitude and opposite phase of the
forward current and reflected current at the ends of a 1/2WL
dipole is the reason that the ends don't radiate much. The
two currents are acting like transmission line currents and
thus any radiated fields tend to cancel because of destructive
interference.

The forward current and reflected current are in phase at
the feedpoint. Their fields interfere constructively and
thus radiation is maximum at that maximum current point.

In your case magnetic energy remains with the radiator which is a loss
that is unaccounted for ! This loss does not occur with a diamagnetic
materials. Very simple my dear Watson.

then why do my ferromagnetic antennas work better than there diamagnetic
predecessor??

If a design is planar it just cannot be 100% efficient as when all
forced are accounted for.

nothing is 100%

who is barred?? i've just been busy with real antennas getting ready for
winter. i will be gone in another week or so because verizon caved in and
will be dumping usenet. maybe i'll resurrect myself with some other
service, but none that i have to pay for, you aren't that much fun.

awww, i'm sure there are others who get as much of a laugh at your rantings
and random phrases as i do! keep going!!

This is when all current is transferred to the particle encapsulation
and no current travels
in the radiator carrier ie Radiation resistance is 52 ohms
