We are talking about 75m bugcatcher coils, Tom, not one special

bugcatcher coil, then they fail in reality. You assertions have
to be valid for all cases or else they are invalid. Finding one
special case that agrees with your assertions, e.g. your previous
toroidal coil measurement, may boost your ego but doesn't really
matter one iota in the overall scheme of technical fact.

Actually that statement proves YOUR theory wrong Cecil, not mine.
I'm saying that in an antenna of fixed length with a fixed coil
location on a given frequency, I can change ONLY the coil design, still
maintain resonance, and have phase delay of current change
significantly.
YOU are the one who appears to be saying all coils and stubs are equal
within a small range.
The theory I believe to be correct is the capacitance from the inductor
to the rest of the world compared to termination impedance determines
phase shift in current and current taper. What is it you think
determines current phase shift at each end and current taper?
Explain the logic behind your idea in a way that makes the toroid work,
or a compact equal form factor inductor have very low phase shift
compared to an entire helice.
My example works in every case. Your's fails, and you cannot just toss
out the obvious disagreement and expect people to take you seriously.
