Pardon me while I learn from this discussion. The 450 ohm antenna is designed to be tuned by using exactly 1/2 electrical wave lengths to match both the transmitter and antenna. This should mean that any differing feedline should work equally as well (except for the losses) if I am correct....

What you are missing is that first piece of matching section which can be any length less than 1/2WL. After that first piece of matching section, you could indeed switch to a different characteristic impedance. Congratulations, you have just invented the G5RV. :-) Fred, I believe that you and Cecil are 180 degrees out of phase. Did someone make a type-O? -- 73 for now Buck N4PGW |
