You really mean that Roy, or am I misreading?
I agree that no 'average' value of power is reflecting, but with a
mismatch at the antenna terminals, voltage/current is definitely
sloshing back and forth on the line making standing waves at .25L
intervals that we can physically probe and measure...


It depends upon one's definition of "power". A purist
will argue that it is not power until it is dissipated
and steady state reflected power is not dissipated
until power is removed from the source.

The question is: Are the ExB watts associated with a
reflected energy wave defined as "power" or not.
