By definition and by physics, we cannot have charges flowing two
directions at once at one point.

A charge carrier cannot be moving in two directions at
the same time. Two currents can certainly exist in opposite
directions at the same time. That's what forward current
and reflected current is. If you want to deny the existence
of forward and reflected current, be my guest.

This is precisely the current we would measure with a current meter
sampling the magnetic field, it is the current we would measure
sampling radiation, and it is the current that would determine phase of
the radiation or induction field.

Yes, but if it's phase is unchanging, which direction is
it flowing? When the forward current and reflected current
are of equal magnitudes, which direction is the phasor sum
of those two currents flowing?

So please expain to use, even if we allow a conductor to have TWO
voltage gradients of opposite polarity over the same linear area of
conductor, why Cecil's Current is important.

I have told you and W7EL about a dozen times before. One
cannot use standing wave current phase to measure the phase
shift through a wire or through a coil. Any such attempt
will fail. Yet, that is what W7EL has reported as technical
fact for about a year now.

Also, tell us how we can measure and prove in a repeatable test, the
two-way charge movement exists.

Please stop implying something that isn't true. There is no
two-way movement of single charge carriers. The current is NOT
the same thing as the charge carriers.

Either you are creating diversionary conundrums, or you should be able
to explain how we can have charges moving past a point in a single
conductor that are moving both directions at one instant of time.

Please cut the BS, Tom. Individual charge carriers don't move in
both directions at the same time. The forward and reflected current
waves move in both directions at the same time, unaware of each
other's presence until they encounter an impedance discontinuity.

It is obvious that you don't understand forward and reflected EM
waves that can exist on a wire or even in free space. Please crack
open a textbook on such. Ramo and Whinnery is a good reference.

The almost universal measurement method of current is magnetic.
Suddenly Cecil's Theory of Current renders universal measurement
methods obsolete!

This is technical discussion and has absolutely nothing to do
with you or me.

NEC uses current and voltage, not wave theory. You attempt to use an
engine that uses what you say we can use to prove we are wrong in using
current when there are standing waves!

How do you explain EZNEC getting the same answer as the distributed
network model at: http://www.qsl.net/w5dxp/travstnd.GIF? And while
you are looking at that graph, please explain how the flat phase
of the standing wave current can be used to measure phase through
a wire or a coil.

Don't you think you should have understood the NEC engine used in the
program before using it to prove we cannot use current without
reflections?

No. EZNEC agrees with the distributed network model. That's all
I need to know about it.

Yes, absolutely. If you don't understand that, you'd better review
basic transmission lines and quit wasting everyone else's time giving
assignments.

Exactly how does the displacement current to ground get outside
of a coax line with no common-mode currents?

If we stopped that third path, the current would not change.

Assume one amp of forward current and one amp of reflected current
inside a piece of coax with no common-mode current. There's no
third path to ground, yet the standing wave still exists, with
current nodes and current loops. No third path to ground is
required.

Answer the question Cecil, how can we have charge movement over a small
length of conductor (in terms of the wavelength) in two directions at
the same time, or a drift velocity in two directions at once?

Your straw man is noted for all the world to see. A single charge
carrier cannot move in two directions at the same time. But if
you are denying that two EM waves can move in opposite directions
at the same time, please just come right out and assert such.
