[TowerTalk] Double Coax Runs to Reduce Loss

[Jim Brown]

Also beware of vendors selling that shiny red/black zip cord -- the 
copper is often several gauges smaller than it's advertised, with 
thicker than usual insulation. And zip cord is a terrible choice for 
power and loudspeaker wiring, because it's a sitting duck for RFI.

FAR better to use twisted pair, which is much harder to buy but easy to 
roll your own. Simply buy lengths (or spools) of black and white 
stranded THHN, stick one end of both conductors in a hand drill, the 
other end in a vise, and run the drill slowly for a while. Let the 
twisted conductors sit overnight in the drill and vise. They will try to 
untwist, but letting them sit minimizes that. The twist will not be 
perfectly uniform, but it will be plenty good enough.
