Of course loading coils can be expressed in electrical degrees. But
extrapolating this to mean that a loading coil has the same properties
as an antenna with the same number of "degrees" has no justification.

Yuri's theory was shown to be false not only by many of the good
technical arguments given here in this thread, but also by a careful
measurement I made over a year ago. I built a 33 foot high vertical and
loaded it at the bottom with a toroidal inductor to resonate it at 3.8
MHz. The coil "replaced" 33.4 electrical degrees of antenna. Yuri's
theory predicts that the current at the top of the inductor should be
16.5% less than that at the bottom, with a phase shift of 33.4 degrees.
What I measured was a current drop of 5.4% and no measurable phase shift
across the inductor. Both the description of the setup and the detailed
results were posted on this newsgroup on Nov. 11, 2003, with the subject
title " Current in antenna loading coils controversy - new
measurement". Anyone can find those postings with groups.google.com.

Yuri's response, also on Nov. 11, 2003 was to complain about my
methodology, declare that he was still right, and state "I will measure
things myself, try to verify previous measurements and then come up with
conclusions and 'theory'."

On Nov. 12, 2003, he posted: "I will be making snap-on current probe,
which will make it easier to slide along the element and observe the
current without the disturbance to the antenna and will be a bit
different over the thermocouple meters. Just need a bit more time."

Well, it's been over a year now, and all I've seen is the same
unsupported theory with no evidence to contradict the contrary evidence
which has been presented.

When a belief stays fixed in spite of both contradictory solid theory
and measurements, it fits into the category of religion, not science. So
it's appropriate that Yuri speaks in terms of an explanation being a
"heresy". What's next, "good" and "evil" theories?

W8JI and other unbelievers that antenna and loading coils can not be

Band DXing book, 4th edition, page 9-47, Fig 9-58, showing loaded vertical
with mast being 40 deg. 59.6 ft. long, loading coil of 144 uH taking
(replacing radiator of) 40 deg and whip of 10 deg and 14.9 ft long, for
overall 90 deg electrical and quarter wave resonant system.
Soooo, to anyone outside of "equal current worshippers" it is obvious that
coil is replacing 40 deg worth of radiator and it would drop equivalent
amount of current across the coil that corresponds to the length of radiator
that coil replaces, because rest of the "straight" radiator FORCES IT TO
DO - because of standing wave and current.

Such a heresy!
Theeere is your sign!
