Obviously

The original posting made no assertions and was simply a URL
which didn't respond when I tried to access it. The subsequent
postings seemed to be concerned with radiation resistance so I
didn't even read them. How does radiation resistance affect the
loading coil discussion? It has already been proven that EZNEC's
lumped circuit model doesn't work for Kraus' real world loading
coils. What else is there to say?

A lot. Besides, it hasn't been proven, at least not by you, that
Kraus' loading coils work the way you seem to think they do.

What the whole damn lot of you have forgotten is the electromagnetic
coupling which occurs between the antenna wire sections on either side of
the phasing coils, especially when the adjacent wire sections are supposed
to be in anti-phase with each other.

Yes, but soon we'll all have forgotten more than you ever knew. ;-)

Absolutely correct. No analysis is complete without taking that into account.
I was hoping no one would bring that up, however, since I've
been having too much fun goring Cecil's rather fragile ox.

Don't you mean Kraus' "rather fragile ox"?

Kraus' phase-reversing coils work the way he says they do.
A high impedance trap blocks current if it is looking into
a low impedance because it is a high impedance. But if it
is looking into a high impedance, like a 1/2WL element, it
simply reverses the phase of the current, like a quarter-wave
shorted series stub. Would you like me to send you the EZNEC
files that demonstrate the phase reversal using stubs or
multiple sources?

Not worshipping, Reg, just respecting. He's one of the few
references I have for BBQ'ing those sacred cows.

He can't work out the proofs himself so he has to
appeal to a higher authority and hope it all comes out
right.

I hope that Kraus is right. You hope that Kraus is wrong.
Guess which hope has the highest probability of being true?
I have presented a reference with which I agree. Now it is
your turn to present a reference that disagrees with Kraus.
Good luck on that one.
