Cecil,

Suppose I do the following experiment: a source of unknown impedance,
connected to a shorted 1/4 wave line through a ~50 Ohm series resistor. When
looking at the voltage on the two ends of the resistor with a 'scope, I
expect them to be the same value, with no phase difference. Do you think
that would be enough to satisfy the nay sayers that the source is delivering
no power? I am *not* talking about you.

In retrospect, my posting here is probably a variation of what Roy posted a
few months ago. Didn't mean to rip him off. BTW, I was in error when I said
the line charges up in 1/2 cycle; that would be true only if the source
impedance was 0.

There are an infinite number of possibilities between the rails of 100%
re-reflection and zero re-reflection. I suspect a PA obeys the rules of
the wave reflection model set forth in Ramo & Whinnery.
