No, I am saying that a fixed length line, mismatched at the far end, and of

Changing the length of the ladder-line changes the
50 ohm SWR seen by the source. That is a well known
fact. But that doesn't mean the SWR on the ladder-
line is changing. It simply means that the impedance
is being transformed by the constant SWR circle.
