Yuri, the inductor I put at the base of the antenna "replaced" something
like 20 - 45 degrees, depending on how you judge the effect of the
mounting arrangement. Barry, W9UCW also measured a substantial current
magnitude difference between the ends of a base-mounted toroid.

So, as a successful and award-winning engineer, what do you calculate as
being the ratio of currents across my inductor, and how did you
calculate it?

That's a pretty good theory, Yuri. I'd like to know where you got
this "Cosine law" you keep talking about. I can't seem to find
mention of any such _law_ anywhere but on this newsgroup. Does
that mean I should throw away my method of moments software
because I don't need it any more? And what is a current
drop? I've heard of voltage drops and cough drops but never
current drops. Finally, how do you measure the "current in
the radiator (in degrees)?" Why not use amperes like everyone
else?
I won't believe your theory, Yuri, until you and Cecil take the
time to present it in terms of field theory. Since you guys have taken
EM classes in college you should have no trouble doing this, right?
