I'll drink to that. Consider a transmitter connected to an antenna
tuner by a piece of 50 ohm coax where the SWR is an ideal 1:1 on that
short piece of coax. There are no reflected waves on the coax.
Therefore, no reflected energy reaches the source. Energy transfer is
a one-way process on that flat piece of coax. Except for efficiency,
the source impedance doesn't matter. Whether the source impedance is
10 ohms, or 50 ohms, or 200 ohms, dissipative or non-dissipative,
reactive or resistive - just doesn't matter. All that matters is the
voltage delivered to the 50 ohm Z0-match at the tuner input.
