Roy,
If a transmitter produces r-f power, and a load connected to that
transmitter via a transmission line dissipates any of that r-f power, then
would you not agree that such an r-f transmission line conducts at least
whatever r-f power is dissipated by that load?
And if such a transmission line can conduct power in one direction
(incident), it can also conduct power equally well in the opposite direction
(reflected), until the net result of incident + reflected causes line
failure.
When the Zo of a transmission line matches the Zo of a load at its far end,
then that far-end Z absorbs nearly 100% of the power delivered there by that
transmission line.
If those impedances are not matched, a reflection is generated that may lead
to the real-world, destructive and periodic effects on the transmission line
that I reported from personal experience, earlier in this thread.
