It seems a lot easier to just run ladder line to your loop and let a balun equipped tuner deal with matter. It is very hard to get balanced RF transmission lines that are anywhere near balanced. For transmitting, a little imabalance only sprays RF all over the place, but any imbalance on receive will let noise enter the system. A friend has a cabin in an isolated location with no power, telephone or cable TV. And a balanced line, even AC zip cord, works great for receiving. But in every location with AC mains power that I have tried to use balanced zip cord, 300 Ohm (unsheilded) or 450 Ohm lader line, I have experienced lots of noise. I have had good results with 300 Ohm shielded, but when compared to 50 or 75 Ohm coax, there was no perceptable difference. Local noise, generated in the SLWers home, is often the biggest limitation and anything you can do to reduce it, either at the source, or by keeping out of the feedline will help pull in those weak signals. A tuner mounted at the antenna, with a remote control would be nice to play with. But a matching transformer is a lot easier and cheaper, and for most of us is more then "good enough". Terry |
