The current reported by EZNEC isn't referenced to source phase. The
phases of all currents and voltages -- wire, source, and load -- are all
referenced to the same arbitrary point. Source phase can be assigned by
the user to any value relative to this point.

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.


As far as I can tell, Cecil has never been quite able to understand just
what EZNEC reports. EZNEC doesn't need several different definitions of
current to suit the theory du jour or to do its job, so it doesn't
report "standing wave current" or other fruits of The Gifted One's
overly fertile imagination. It simply reports current. Anyone not
acquainted with this concept can refer to any basic text on electricity
or physics. What EZNEC reports is exactly what you'll find there.
