This is freakin unbelievable.
You think you are making fool of me and rest of us? You are not answering
questions, nor engaging in the exchange. You keep pulling out crap, like
first the current is equal, then
"" I can change current difference at each end of the inductor all over
the place depending on the design of the loading coil, with NO change
in the loading coil position or antenna lengths."
You are getting tangled in your own webs!!!
Tell us what is wrong with W9UCW setup and results. Where did he screw up,
what is wrong, and show what you have measured in THE SAME type of setup.
Not freakin W8JI coils, not at the base, no weird frequency, not twist and
dance.
Just take 40m shorted vertical, make it resonant with DECENT coil like he
has about 2/3 up the mast, stick the RF ammeters at both ends and give us
the readings. You have the pictures, you should be able to replicate the
setup.
Then you tell us that the current is the same at both ends, show us the
pictures and describe your setup, meters, frequency and results.
This goes for the rest of the "gurus" that insist on the same.
Then model the loading coil as a solenoid or loading stub of same inductance
in EZNEC and show us what you get. Cecil did it, and the silence is
deafening!!! Can you explain what is "wrong" with Cecil's examples?
Looks like Belrose should get another pHDuuhh for starting all this
misconception and misinformation in ham literature. Pathetic is that some of
the "gurus" that should know better, are on the same bandwagon to la-la
land.
Stop crap and twist and dance, answer the freakin questions or say nothing.
We are not idiots that you BS with "you don't know what I mean by
impedance".
So what happened to impedance? Now you know what it is, or is pink electron
displacement capacitance current phasor phase mumbo jumbo?

Let's back off one more giant step back to measurements. Show where
W9UCW
was "cheating" in his test setup, pictures and comments at
http://www.k3bu.us/loadingcoils.htm
where he shows clearly that RF current drops significantly across
(through)
the loading coil, just like it drops across (through) the resonant
antenna
(piece of wire or tubing) from max at the base, to zero at the tip.
Displacement currents in the inductor and the very high reactance of
the very short antenna above the coil explain current difference.
Current cannot vanish Yuri. It has to have an alternative path.
Have you heard of standing waves?
I can change current difference at each end of the inductor all over
the place depending on the design of the loading coil, with NO change
in the loading coil position or antenna lengths.
That is the progress, first current can't change, now you can make it.
It is the theory you have, that the current is tied to the "missing
degrees", that is wrong.
Without displacement currents there is no current difference at each
end of the coil, it is not caused by "missing degrees. It is caused by
the capacitance above the coil being very low and the capacitance of
the coil to the outside world being much larger. The current is not all
gone in the first few turns either. It is a series reactance/shunt
reactance problem.

PRICELESS!!!!!
So WHAT IS THE CURRENT AT THE TOP OF THE RESONANT 90 deg (any) VERTICAL?
Same as at the base, because "Current can not vanish Yuri"?
You are jerking our chain or have a real problem.
Suggestion: do some reading on impedance, resonance, standing waves, current
and voltage distribution along the antennas, and look at the current curves
in books and as produced by EZNEC. Looks like you have no clue how antennas
work.
You can have another "last word" that will "show" that you "know" what you
are talking about.
