How do you propose that this occurs without having an effect on the
forward and reflected waves which comprise the standing wave?

It obviously has an effect on the standing wave. In no
way can Wes's current waveform be called a cosine function.
However, we know that the current and voltage are in
phase at the feedpoint and at the tip of the antenna.
It is impossible for them to be in phase anywhere else.

It would be better if you provided some sort of demarcation between the
well known facts and the pensive speculation in your posts. :-)

It's all simple physics, Jim, aided by a measured IQ of 168.
