PICKY, PICKY, PICKY!

Mea culpa.  I was wrong O, GREAT MASTER and therefore all I said was 
incorrect.

Sheesh!  Gotta pick at something, huh.

Of course, the Smitch Chart needs to be normalized to whatever impedance 
system you are working in be it 1 Ohm, 50 Ohms, 75 Ohm, or 10 MegOhms.

But generally when an RF engineer talks about the 50 Ohm point on the 
Smitch Chart, he means the center since 50 Ohms is the standard for most 
RF communications (Television is an exception).
