I haven't been following this particular discussion of "standing wave
antennas" vs "traveling wave antennas" ...

It certainly has a bearing on whether standing wave current
can be used to determine the delay through a 75m loading coil
like you have said it can. Please take a look at the current
phase reported by EZNEC and tell us once again how an constant
phase at all points on the antenna at any particular time can
be used to measure delay through the wire.

This is *not* the SWR on an antenna ... An alternate SWR Z0
value can be specified so you can also see what the SWR would
be on a transmission line of some other impedance.

Richard C., are you reading this straight from the horse's mouth?
