Never heard of a wireless rotor
All rotors I've ever known of use wires to both power and direct the rotor to turn one way or the other. The only exception is with Ku-band satellite motors for FTA that use power supplied from the receiver and runs through the coaxial cable. It would be nice to have a concept like this for OTA antennas. Instead of flipping a switch on the rotor and changing the channel or punching in a number on the rotor and then punching in the channel number on the receiver, you could instead punch in the RF on the receiver and through software settings programmed by the user, the rotor would move to the optimal point for that frequency. The best rotor I know of is made by channel master. It is a remote controllable rotor that a little box hooks to via three power wires. It's programmable with up to 69 channels, which is the total number of OTA frequencies currently available by the FCC until they reduce the amount to 52. It's more pricey than others, but this baby will allow you to program to one degree of accuracy compared to those turn dial rotors where you have to sort of guess where the hot spot is. It's amazing how much difference a single degree of turn can make on a weak signal. Oh and this rotor also synchronizes itself after a total of 50 turns to keep each degree aligned correctly. You can also synchronize it yourself as well.
