You only need to know the math to understand HOW the Smith chart works,
but not to use a Smith chart and get real world answers to real world
problems.

I never will appreciate the usefulness of a Smith chart because all I ever
did with it was to determine if all the points fell on or inside the nominal
3:1 circle that was inscribed on the chart. The plotted impedance points
came off an analyzer that was sequentially tuned to a comb of frequencies.
I never did any math except on my time card: 8+8+8+8+8=40.

I understand that the trace can be rotated and shifted with the inclusion of
reactive components at the feedpoint but that was the contracted
responsibility of others. Someday, maybe I'll learn it but so many other
things are already lined up, waiting for me.
