I don't understand the reluctance to use 50 to 75 ohm impedance
transfomers. I built two of the ones featured in all recent ARRL
Handbooks - took me about an evening, and total cost was about $30
including the boxes. They work GREAT. When I put them into my system, I
had one in backwards because of a stupid mistake, and the resulting SWR
was 2:1. I figured out what was wrong and turned the transformer around
and all was beautific.
I run 1500 watts to them and they stay cool. I can't imagine why anyone
would bother to do it any other way!
