which makes the resistor capacitive or inductive?

Nope, since the current is in phase with the voltage, it makes the
resistor resistive. That means when you look at the voltage waveform
across a one ohm resistor, you are also looking at the current
waveform.

You're arguing asynchronously. You're arguments bear no relation to the
points being made by your correspondents.

Nice copout, Jim, really nice. The point is that the standing wave
current indeed does look like a sine wave with magnitude, direction,
and phase, and not as you implied, like an unchanging DC parameter
that just stands there.

Not a DC parameter. An AC amplitude. Like the I in i(t)=I*sin(w).
You plotted I as a function of position for your antenna standing wave
plots. It's the topic of discussion.

That was a snapshot by EZNEC, frozen in time, Jim. Here's what the standing
wave current looks like when it is not frozen in time. That's the topic of
discussion that everyone seems to want to avoid. Standing waves don't stand
still. They probably should have been called "looping waves".

Right. It's what EZNEC shows, the same EZNEC Cecil just used to
try to prove his theories.

The standing wave current at a loop
changes sign, and therefore direction, every 1/2 cycle.

Uh-huh

Don't you guys understand that EZNEC gives a freeze-frame snapshot of
the current referenced to the source which is specified by the user?
For instance, when the source is 1 amp at zero degrees, EZNEC shows
a freeze-frame snapshot of the current referenced to that source
current. Why don't you guys know that? Just because a freeze-frame
snapshot stands still doesn't mean the actual current is frozen in
time. Good Grief! Try to understand the following web page and then
come back and tell us that the standing wave current is not changing.

Yep, and you're changing the subject. How does that wave, that flip flops
like a jump rope, move in and out of your coil?
