Another 'speriment occured to me, for those who think the coil current
MUST be different at the two ends by the amount corresponding to the
antenna section it replaces: try making the antenna diameter large
compared with the coil diameter, say two to four times the coil
diameter, while maintaining the same lengths, and see what happens. I
suppose you'll have to adjust the inductance of the coil, but keep its
diameter and length the same. If the current at the ends of the coil
remains nominally the same as with a thin antenna, then I'll say you're
onto something. If on the other hand, the current becomes much more
similar at the two ends of the coil, that will be evidence of a
different effect--in fact the effect that I expect is actually
accounting for the difference.

Perhaps someone would like to try that in NEC2 or NEC4 and share the
results, if nobody is actually up to building the antenna and measuring
things.

I'm afraid that the proponents of the alternative theories aren't
subject to either modeling or measurement results. There's already ample
theoretical, modeling, and measurement evidence to show that the theory
is faulty; further efforts would be a waste of time.
