I have run across this recently talking to some guys in my general area, and I thought it was interesting. I have a ground mounted receiving antenna located 350 feet from my shack that I have connected with RG-6. I had thought one day of trying to transmit on it but I did not have an F connector to UHF adapter, so it never happened. Talking recently to some fellows, I found out that several of them have been using RG-6 for incredibly long runs and that they were happy with the results. None of them had any idea as to how much loss there was on the feed lines, just that they were able to receive quit well and talk to anyone that they could hear. The lengths are from 800 to 1300 feet of RG-6 and one fellow is running 900 watts on an 1100 foot run.( That's 900 watts into the feed line, watts on the far end, ? much lower for sure.) I personally have not verified any of this but know others who I trust that claim it is in fact true. Talking to one of them 3 nights ago that was giving me an excellent signal for the range, had 900 ft and was running 400 watts. He says that as far as he knows none of these fellows are using a tuner, they have been adjusting the match with length alone. If all this is in fact true, I find it to be a very interesting and cost effective alternative for long runs. Also, later that same night another regular on the frequency that I have not been able to hear before, came in loud and clear with an S-5 on his newly extended RG-6 mountaintop line. I know that the loss will have to be incredible, but locating the antenna in an otherwise un accessible area cost effectively may be worth it. I live in the very bottom of the Ohio River valley, and run 500 watts into a beam. I can drive to the top of the hill 1 mile away with a 40 watt mobile and talk to and hear people that I can not at the base. Antennas like Real Estate are location, location, location. Has anyone else tried transmitting through RG-6?
