Is there a procedure? I find myself wasting a lot of time fumbling around with the antenna rotator going back and forth and and running the auto scan numerous times!
Mine is plugged into an open TV port on my distribution box. I just turn it on and hang it outside the cabinet so I can see from upstairs while I am turning the antenna.
Rotate antenna until I have the maximum strength, THEN I do the channel scan on the TV. Work great.
Usually only need to do it once unless I am between TV towers and looking for a specific station.
