Standing-wave current phase changes hardly at all up and
down a stub with losses or a wire 1/2WL dipole.


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.

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.

For those who don't understand Jim's diversion above, EZNEC
sets t=zero as a reference and then reports the phase. Jim
knows that and is just trying to hoodwink the uninitiatated.
His motives for such remain a mystery.
