Mass market options for multi-conductor cable are pretty limited. I used 
two runs of Romex for most of the 350 ft run to the top of my tower for 
a Yaesu rotator. I found a suitable cable for the 3-el SteppIR from a 
ham whose wife ran a biz manufacturing and distributing specialized 
audio cables, most of which need twisted pairs. You may know him -- Bill 
Steffey, NY9H, was a mfr's rep for a lot of top audio lines, and also 
worked in broadcasting in Chicago 20-30 years ago.
