Standing-wave current phase changes hardly at all up and

That is correct to the same extent that t in the equation above
"changes hardly at all" with time.
The phase is referenced to the source phase, as it is in EZNEC,
but you already knew that and just want to perform your usual
diversions away from the technical facts.
Actually, I'm trying to figure out what technical meaning there is to
be obtained from your repeated observation "Standing-wave current
phase changes hardly at all up and down a stub with losses or a wire
1/2WL dipole." The phase of the standing wave varies with position
from one perspective, and with time from another, and with amplitude
from yet another. If you hold t fixed, then amplitude and position
remain variable. This is a revelation?
I have said at least a dozen times that the current phase
I am talking about is the same as EZNEC reports. If you don't
like what EZNEC reports, take it up with Roy.
One should be careful not to invite comparisons to a craftsman holding
his tools responsible for poor craftsmanship. ;-)
