I cannot explain every detail of Barry Boothe's measurements, but I know
for certain that the true explanation is the one that obeys all the laws
of physics and circuit theory, down to the last detail.

What you have, Yuri, is an "explanation" that uses those laws in some
parts, but twists or ignores them in others. That cannot possibly be
correct.

You can't explain reality, but you have good arguments to support your
"theory".
Now you can plug in solenoid/helix into EZNEC 4.08 and see for yourself
what'sup (See my other recent post). We are not claiming that hairpin is exact
replacement for lumped inductor, but some properties when inserted into
modeling program illustrate better what is really happening (current is NOT
equal at both ends of the coil).
Take the fricken RF ammeters and stick'em in the coil's ends, you have
excellent current probe on your web site. As you can see from W9UCW
measurements and my recent example of 10m loaded vertical that there is
significant difference in the current across the loading coil (not equal) and
lower you go on frequency when antenna gets short relative to wavelength used,
the more pronounced the effect is.

Significance? As ON4UN points out, efficiency is proportional to the area under
the current curve, that is important for loaded antenna designers, and if they
understood this, we would not have the flood of "magical" wrongly loaded,
shortened antennas (like Vincent/UoRI "patented" crap).

just another "dumb" ham
