OK __ I won't post here anymore. I once was an Amateur when I was 14.
I thought that I wanted to get back into the hobby now that I am retired.

so my terminology is a little rusty. VSWR = (1 + abs(rho))/(1 -
abs(rho))

When the reflection coefficient rho is +/- 1 the VSWR is infinite. When
rho
= 0 the VSWR is 1:1. A VSWR of 1:1 corresponds to the unit circle at the
center of the Smith Chart.

Hi Bob, I have never taught at the University level myself, this is an
"Amateur" newsgroup. If you look at the Smith Chart, 1/2WL reflects
back the identical load impedance, no matter the transmission line
characteristic impedance (neglecting losses). If you have a 1/2WL 600
ohm line driving a 50 ohm load, then you have reflections (SWR), but at
the source end, you see 50 ohms (V and I in phase).
