Quote:My questions are- what is the length of twisted pair lead in before noticeable degradation of performance? What should the twist per inch be for best performance? Any length of transmission line has loss...

For a twisted pair, #18 MTW, twist 1 turn in 2" should yield roughly 72ohms balanced. Warm the cable with a heat gun to "set" the insulation to reduce unraveling. Will want to use on a radio with a balanced input if practical.
