Less energy indeed lowers the current amplitude.


Agreed.


Note that we agree on almost everything.

w7el "measured" the phase shift in current
that doesn't flow.


:-) He's good, but he ain't that good. Besides, his meter is the same
as yours in that it only responds to waves that travel and currents that
flow. ... I've said my piece.


Exactly, the more you post, the more obvious agreements
we have. The following current is the one that dominates
a standing-wave antenna.

I(x,t) = Imax*cos(kx)*cos(wt)

Such a current cannot be used to calculate delay from
phase shift in a wire or in a coil. Yet, that is exactly
what w7el and w8ji did.

Are you leaving the thread because you are on the verge
of proving w7el wrong?
