I hope this helps in understanding why the SWR at the input of the 72-ohm line
is 1.44:1, and NOT 1:1.

Very good stuff, Walt, as usual. It is possible that Gary
misunderstood the question. He apparently thought the question
was: What SWR will a 50 ohm SWR meter indicate and of course,
a 50 ohm SWR meter will erroneously report an SWR of 1:1 at
the 50 ohm (current maximum) point on the 72 ohm feedline. If
we move the 50 ohm SWR meter to the 103.7 ohm (current minimum)
point on the 72 ohm feedline, it will erroneously report an SWR
of 2.1:1. But, on the 72 ohm feedline, the SWR is, of course,
1.44:1 at both the 50 ohm point and the 103.7 point and at all
other points up and down the feedline (neglecting losses).
