Stand by your guns, Jimmie, you are correct. It's just
that some otherwise intelligent people on this newsgroup
have forgotten everything they ever learned in
Fields&Waves 101.

In an antenna physically shorter than 1/4WL, there is
no way that I know of to get the reflected wave back
in phase with the forward wave at the feedpoint without
the reflected wave making an electrical 180 degree round
trip, i.e. 90 electrical degrees in each direction.
