Roger is wrong too, and Richard is not.

Electrostatic indicators don't measure current or charge movement, they
measure voltage or charge displacement.

But what I really want to know is how Cecil can have current flowing
both directions at the same instant of time in a single point of single
conductor, can dismiss displacement currents as trivial things that can
be ignored when they are required to define the most important aspects
of transmission or antenna behavior, and say the very thing that is
used to measure current suddenly doesn't measure his imaginary two-way
reflected and forward current's vector sum.

That's what is really important, especially in light of the fact Cecil
is quick to play superior.

Anyone who is really superior should be able to walk us through the
physics of two-way current and tell us why dosplacement currents don't
matter, and explain his magical transmission lines and antennas without
displacement current in a way that we all understand.

Cecil can't prove that charge can move in two opposite directions
at once. No one can. It's impossible. He's always had problems with
superposition, believing the constituents of a standing wave have
more reality than the wave itself.
