Not only does Terman give voltage and current diagrams, he gives a phase
diagram. It shows that whenever the voltage or current crosses the zero
axis (changes sign) the phase angle changes abruptly by 180-degrees.
Phase is unchanging between these inflection points. This agrees with
what Cecil has said all along in this discussion.

Kraus agrees. Yet W7EL used that unchanging phase to measure the
delay through a loading coil. What's wrong with that picture?

Some people, who no doubt have recognized their technical errors,
simply refuse to discuss the technical subjects. Ian, OTOH, seems
open to discussing those topics so please don't be too hard on him.
An honest person deserves respect whether he is right or wrong.
