- 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 inc

- I dont understand the need for these boxes if you are feeding monoband yagis. The ARRL Antenna Handbook and ON4UN's book both describe how to use asynchronous transformers out of coax. I use them for

- Raises an interesting question, but one beyond my quantitative abilities. Assuming the autotransformers are built well - adequate wire size, proper core, big-enough box, etc. - what is the expected l

- It's been interesting following this thread for the past few days. In Pete's reply he almost said what I'm about to: Why bother with the transformers at all?? I have many runs of 75ohm hardline runni

- Here are a couple of notes that may be useful in deciding whether or not to use transformers with a run of 75 ohm cable with a 50-ohm antenna and a transmitter/amp designed for 50-ohm systems. Assum

- just another thing to throw a monkey wrench in the works... do some rough calculations: compare wavelengths at the two busiest frequencies on 80m in contests 300/3.5mhz = 85.7m 300/3.8mhz = 78.9m dif
