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 :-) --- Jeff WN3A --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
