Larry: I'll definitely look that over.
Bill:
You did well. For most amateur radio operators, I suspect a VNA will be
difficult to fully understand. Very seldom in the amateur magazines
is there mention of the complications that phase introduces,
and hardly ever are there calculations that include phase.
Few evaluate an antenna any further than finding the SWR.
I'm trying to write a short concise description of a VNA that introduces
the concept of phase, impedance, and complex numbers. It isn't easy.
Which explains why most tutorials assume this stuff is already understood.
Once I get something down I'll poke around further and see if
it has been done better. Probably has, but it is a good exercise for me.
Minor details pop up when trying to explain something like this,
demonstrating that I don't quite understand it as well as I thought.
