Not even if the frequency is known and there's a standing wave current
loop at one end of the coil and a standing wave current node at the
other end?

Total current phase is the context of my posting above.
We were talking about total current phase, not total
current amplitude. To be precise, the statement should
read: "That's why total current phase cannot be used
to measure a delay through a coil in a standing-wave
antenna". It is difficult to post context-free English.

W8JI and W7EL both used standing-wave current *phase* to
try to determine the delay through a coil. That is an
invalid measurement concept. If they had used the standing-
wave current amplitude instead to calculate the phase
shift, they would have gotten much closer to a valid
result. But they are arguing about current amplitude
drops which are simply relative phase shifts between
the forward and reflected current.
