Hi Ian,
Your parenthetical is EXACTLY what devastates the logic of forcing the
real inductor to observe a constant angular length according to
Cecil's misapplication of the so-called Corum rule. It also reveals
the problem with Tom's measurement. However, negating Tom does not
validate Cecil - and vice versa.
As for the implicit (or explicit) expectation of Kirchhoff being
satisfied, that is a lose-lose proposition from the get-go as these
discussions violate the necessary zero scale of wavelength, something
you also covered quite well:
The main difference is that the real-life
coil occupies a significant fraction of the total physical height of the
antenna.
