hello all. new to this over the air antenna stuff so please excuse the dumb questions. I think of read so much stuff I'm dumber then when I started. I figured I dive in headfirst so I bought it Channel Master 3020. so now I'm looking for a rotor. I have a rotor off of a house but I don't know what it is, who makes it, or even if it works, or how to power up. Any ideas on what voltage these are to try and see if it spins? 12v-15v? i see most have 3 wires and this one has 4. any suggestions on a good reliable rotor and the contraption to make it turn. something reliable with a remote that maybe shows the direction of the antenna on the remote or tv. I'm going to try and add photo of what i have.
