I'm installing a 60ft tower about 400ft from my house for uhf/vhf. I'm
planning to use a Channel Master rotor which I haven't purchased yet. I've
buried 1"pvc conduit to tower and planning the wire pull for the antenna &
satellite coax plus the rotor cable. From my research 3c/22ga. wire will
control all C M rotors. Since I don't know the power requirements yet of the
un-purchased rotor I can't calculate the voltage drop on appx. 500ft of 22
ga wire to see if it will be sufficient. Can somebody either reply with the
typical C M rotor current/voltage/watts or first hand knowledge of the
correct wire gauge for a 500ft run. Thanks Jeff

What I do is wait for one of the Big Box Stores to have a loss leader
sale on 100' extension cords. They'll usually be 16 ga. -- sometimes
you'll see 14 ga. My rotator requires 5-conductor -- so I buy two
100-footers and parallel the two green wires -- which are usually a
smaller guage than the other two.
