Had an E-Mail as to where to buy ladder line -- 72 or 75 ohm for antenna

Getting a _balanced_ feeder at such low impedance levels is quite
challenging, since a typical twisted pair (e.g.CAT5) would be in the
100-120 ohm range.

You _might_ get something in the balanced 50-75 ohm range by getting a
quad-pair cable and connecting the diagonally opposite conductors
together. Thus, if the original pair had an impedance of 140-150 ohms,
the two pars in the quad-pair cable would give 70-75 ohms.
