Only in a standing-wave environment. The phase of the
current does NOT stay the same in a traveling-wave
environment. That is the key technical fact that the
r.r.a.a gurus have been missing and it can be blamed
directly on the short-cut models which deviate from
reality, sometimes considerably.

In a traveling-wave environment, the phase changes
every inch around the circuit and I can calculate
that phase change for you if you are incapable of
doing it for yourself.
