Current across the antenna loading coil - from scratch

I deny it. There is only current at a point, just as there is only
water jiggling around under a wave on the ocean.
Well, that means denial of the distributed network model.
Please don't be silly. Distributed networks have points. An infinite
number of them. Calculus is used to smoothly move through this
infinity of points. But at any particular point, current is defined
as the rate of movement of charge past that point.
I've been waiting for that to happen. There's no point
continuing an argument with someone who denies one of
the cornerstones of EM wave theory.
So you deny that there are any points (where voltage can be defined or
that charge passes) in all distributed networks?
How strange.
The distributed network model is accepted as a superset
of the lumped circuit model and works when the lumped
circuit model fails.
Yes. And distributed networks are made of a continuum of points.
The fact remains that standing wave current phase cannot
be used to measure phase delay through a wire or through
a coil. There is no phase information in standing wave
current phase.
Yes. That fact remains.
It is a non sequitur in the above discussion, however.
That the standing wave current cycle has the same phase along a half
wavelength of conductor has nothing to do with the current through
that conductor having a point definition (the x in the standing wave
function you keep displaying). And at any point the current is AC,
spending half of the time going one way, and half of the time going
the other way (the positive and negative parts of the cycle in time,
defined by cos(kx)*cos(wt), once you pick and x.
