The spec sheet that M2 sends out on the Orion 2800 rotor plainly states
three number 12 and two number 22 conductors with shield and ground
trace. While other wires may work, the manufacturer has a reason for
stating his recommendations. Since M2 doesn't manufacture wire, I would
assume it is because that is what it takes to work properly regardless
of control wire length.
In my case I have 500 feet. They insisted I shield the two #22 leads to
avoid AC pickup (AC is on the three #12 wires) on the indicator wires.
