yes, rotors require power. but your tuner also requires power, right? and it requires signal from your antenna? i am sure you don't have your tuner up on the roof, right?
the rotor controller can be at/near your tuner, plugged into the wall at/near your tuner. you just run the power wire up to the antenna rotor, the same way you run the coax antenna feed up to the antenna from the tuner.

LOL - OK, I admit, I'm FM antenna-stupid. I just googled around and it doesn't look too hard. Jeez - just another 3 hours on the roof. Thank you for the info.
