"H. Adam Stevens, NQ5H" wrote in message ... zip cord ... Had an E-Mail as to where to buy ladder line -- 72 or 75 ohm for antenna feeder Understand it is scarce in the USA but may be available in the UK Sources anyone? thanks -- One Watt To steal ideas from one person is plagiarism; to steal from many is research. -- Comedian Steven Wright I think if you do the math, any benefit of using balanced 75 Ohm line- especially zip cord with a lossy vinyl dielectric will be lost- especially if not running at low VSWR conditions. My impressiion is that ladder line or balanced line is advantageous when the line is run at a high VSWR. The low matched loss then also means a low loss when run at high VSWR. Dale W4OP |
