Back in my C.B. days in west virginia we ran cable tv coax up the mountains as far as a mile or two to a mountain top antenna. on each end we put 36ft of rg8 or 9913 to acheive a match to the CATV Hardline. I'm not sure if something similar would work for other frequencies. I don't see why not.

As the New Year approaches, i want to express my gratitude for the wealth of information which has come my way thanks to you. As i am a farmer who still works the land with horses, i appreciate the importance in keeping the old, tried and time-tested ways alive; not just for nostalgia's sake but for the time when radios and the written word might be one of the sole sources of communication. If one of those $10,000 digital voodoo boxes breaks down there are only a few select experts that can even diagnose, much less fix the problem. I take off my hat to expose my bald head to all of you!! As an added favour could anyone tell me what sort of toroidal core i would need to transform 75 to 50 0hms. I was given a large quantity of CATV hard-line and read that it would be well to match the impedance to the antenna and the transmitter. Or do you think the Pi-network in the P.A. would be able to match the 75 ohm? I would at leat like to know which cores from Amidon would be the right ones in case i just want to construct a few transformers for experience sake. Thanks so much for any help you can give me. Happy New Year to each and everyone!
