Assuming a lossless 50 ohm line, the steady-state SWR is 4:1 no
matter what the source impedance (assuming there exists a source
voltage not equal to zero volts). Steady-state SWR in a lossless
feedline is a constant fixed voltage ratio from end to end.

Hi Cecil,

WRONG!

The method of computation you employ violates Chipman and any other of
a host of authoritative sources on the topic. If you actually
attempted to verify this at the bench you would "perhaps" find it at
only one point, or at harmonic distances (wavelength specific) along
the line. That means you would stand only a couple of percent chance
of that with a random choice. Guesses are not responsive to the
intent and no points are awarded.

I will leave you to discover Chipman's means to find SWR any where
along any line for yourself. You might enjoy the celebrity of being
the second to do so. ;-)
