An ideal coil can very well be arranged not to radiate or couple to the

very different impedances depending on where each is connected in a
circuit with standing waves. That is what confronts the ordinary loading
coil in an antenna circuit.

Ever wonder why everyone is ignoring the 180 degree phase-reversing
coils described by Kraus in _Antennas_for_all_Applications_? Real-
world coils change the phase of the current from end to end. That
real-world phase shift is all that is required for the total current
at each end of the coil to be different when installed in a standing-wave
antenna undergoing superposition of the forward and reflected currents.

What we seem to have here is a bunch of gurus who are incapable of
admitting that they mistakenly used the lumped circuit model when
they should have used the distributed network model. It's an easy
mistake to make and a hard mistake to admit.
