One exception, in this case we are talking about an antenna tuner with
its output going to a coax line that then goes to the antenna. The
antenna being something near 50 ohms but far enough from it to produce
a 3:1 SWR on its feed line.

So in this case we have 2 transmission lines. One between the
transmitter and the tuner and one between the tuner and the antenna.

I suspect that there is a big misunderstanding of TERMS, going on here.
Definitions are being misused on both sides......

Lets get the TERMS Fixed and Understood first.

Transmitter = Rf Source that has an impedance of 50 Ohms

Transmission Line = Coaxial Feedline between Transmitter and Antenna
Tuner.
Antenna Tuner = Device that matches impedance of it's input (50 Ohms)
to that of the antenna that connects to the tuners
output.
Antenna = Effectivly a wire, or pipe, or other conducting structure
used to radiate RF Energy supplied by the Transmitter to
the feedline.

NOW that we have these definitions settled, Please continue the
discussion.
