I'm surprised that standing waves seem so hard for people to understand.
They're simply a spatial pattern formed by the interference between
forward and reflected waves or, if you prefer, from the solution to a
general transmission line problem with boundary values applied. I'd hope
that even a brief look at a text would make it clear what standing waves
are, and what they are not.
Roy, if you would take a "brief look at a text", you
would know NOT to try to use standing wave current phase
to measure the delay through a 75m loading coil. At any
point in time, the standing wave current phase is essentially
the same value all up and down a 1/2WL dipole including
through any loading coils. Phase does NOT equate to delay
in a standing wave environment.
