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

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.
