Prosistel recommends Cat7E for the motor conductors? Cat7E uses 23 or 22
awg copper wires. I am not familiar with Prosistel rotators and I don't
know the motor's voltage or amperage. 22awg wire has 1.6 ohms resistance
per 100 feet so the voltage drop at the motor could be significant.
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.
