Just as are the currents in the coils.

Is it fair to say that though the diagram may resemble the first
diagram on the page, to some extent, the reason they are similar is
that the second one is incomplete.


I sent you a .gif file giving you the full perspective.

My point is really about whether the subject diagram supports your
argument, especially if it is incomplete and if it misrepresents the
scenario.


The phase shift through the stub is the same as through the coil is
the same as through the wire. It is simply zero according to the
standing wave current phase which is incapable of measuring phase.

For anyone who is foolish enough to believe Cecil when he says that
all phase information is lost when two oppositely traveling waves create
a standing wave, consider the following, adapted from Georg Joos book
_Theoretical Physics_:
consider two traveling waves going in opposite
directions represented mathematically by Ae^i(wt-kx) + Ae^i(wt+kx+d)
where A is the same amplitude for both waves, i is the square root
of -1, k is 2*pi/wavelength, w is the radian frequency, t is time,
x is distance, and d is the phase difference between the two waves.
This is just another way of writing 2Acos(kx+d/2)(e^i(wt+d/2). Notice
that the part cos(kx+d/2) still contains the phase information?
If Cecil were any kind of experimentalist he could easily tease the
phase information out of any standing wave on his antenna system.
