Good point, Wes. A reminder that a 1:1 swr at the input of a lossy tuner
is not proof of a perfect match at the output!

Let's pretend that the antenna (load) Z = 49 +j0. Let's also pretend
that the "tuner" consists of a series 1 ohm resistor.

Looking into the input of the "tuner" we measure 50 +j0. Pretty good,
huh?

Terminating the input of the tuner with 50 +j0 and looking from the
other end we measure 51 +j0. Whoops.

Best have a lossless tuner to play this game.
