The RF Connection developed this cable to fix issues with Orion 2800 series rotors getting out of calibration from motor pulses getting in to the pulse counter. The sense wires are completely shielded with a drain wire that is to be grounded at both ends.

Great cable that solves the problem Time Owned: 3 to 6 months.
I've been using Orion 2800 series rotors for quite some time, they are fine rotors for up to med/large arrays. The issue has always been the DC versions use a PWM scheme to control the speed of the motor and in long runs of normal cable, the pulses in the two motor wires are picked up by the two wires from the pulse counter. This causes the rotor to get out of calibration. This cable has two LARGE conductors for the motor and the two conductors for the pulse are shielded in foil with a drain wire. I've installed it in several locations where I had the calibration drift and the problem has gone away.
