I wonder how easy it would be to display the voltage maxima?
Piece of cake - I already display it with my IMAXMIN.EXE software:http://www.w5dxp.com/goodbad.htm
But simply envisioning a bad point halfway between the good points would be easier.
In some multiband matching systems line impedance is fairly critical, so it is good to know what it really is.
Yes, good for trying to get closer to 50 ohms but relatively unimportant for simply locating the current maximum (purely resistive) points.
Maybe we can get the real line impedance published at the same time the ARRL corrects the loss to realistic values.
I once assumed that The Wireman #562 300 ohm transmitting line had a velocity factor of ~0.9 and cut lengths accordingly - it didn't work. Turns out the VF of the particular line that I had bought was closer to 0.8 than it was to 0.9.
