Back on topic now. Was there ever any correlation between the
measurements made by Cecil and Yuri with the information and tests
performed by Tom W8JI?

Hi Mike,

Well, you have a serious problem embodied in your statement. Neither
Cecil nor Yuri made any measurements. Perhaps Yuri observed some
shrink tube that had charred while he was working power, but actually
that is a stretch (not shrink) as he "observed" this only after the
fact. You certainly have read enough correspondence to observe for
yourself that Yuri cannot describe any system fully, so saying there
were correlations can only come from a heated imagination (more
current in than coming out). If there have been any experimental
details made under observed conditions, we have to credit Tom.

I made self-resonance measurements on loading coils
and standing wave current measurements on a 6m dipole.
W8JI said my measurements were in error. W7EL said
my measurements agreed with EZNEC.

My appologies, so you did.

Cecil, Cecil, Cecil! Shame on you. When will you ever quit changing
what other people say?

Replying to my measurements, here are your words and W7EL's words:

Your measurements are probably wrong. ... After we resolve the
error in current, we can move on.

I repeat: "W8JI said my measurements were in error."

W7EL replied on 3-16-06:
The measurement looks good to me. The phase is exactly what EZNEC
predicts -- constant along the wire.

I repeat: "W7EL said my measurements agreed with EZNEC."

Note that at the frequency where the dipole is 1/2WL and resonant,
it is 180 feet long and 180 degrees long so the number of feet of
wire is also the number of degrees of antenna. Here is my 1/2WL
dipole with current pickup coils installed at points 'x' and 'y' and
FP is the feedpoint,the impedance of which is 60 ohms.

------------------------------FP-------x---------------y-------

Total length is 180 feet. The distance between 'x' and 'y' is 45 feet.
Since feet = degrees in this case, the number of degrees between
'x' and 'y' is known to be 45 degrees from antenna theory. Those
45 degrees are what I am going to attempt to replace with a coil.

So I adjust the feedpoint current to one amp at a reference phase
angle of zero degrees and measure the current at 'x' and the current
at 'y'. The current at 'x' is 0.92 amp at 0 deg. The current at 'y' is
0.38 amp at 0 deg. Already I am not understanding my measurements.


Your measurements are probably wrong.

When did you measure that? After we resolve the error in current, we
can move on.


The measurement looks good to me. The phase is exactly what EZNEC predicts
-- constant along the wire. The ratio in magnitudes we'd expect depends on
the positions along the wire, not just the spacing.
