212+j212 is a Zmag of 300, but that doesn't equate to a 6:1 VSWR with a Z0
of 50 ohms; it's 8.6:1 VSWR. I think the previous poster was trying to
compare two different complex Z's that both yielded a 6:1 VSWR, and his
alternative of 150+j150 was close to 6:1. I get 146+j146 to be as close as
you can get to 6:1 VSWR using whole numbers for R == X, for whatever that's
worth :-)
