I was hoping someone could help me out with some Over the air antenna questions. I live in Jersey City, NJ right outside New York City and am looking to install a rooftop antenna to receive HD signals. I am told that I can receive signals from Phila and New Haven CT from my location but obviously are in different directions. Does anyone have an experience with using a motorized rotator that will change the direction of the antenna depending on which channel I select. How does this work and how is it mounted. I curently only receive cbs and Fox in the New York area. Is this consistent with other people in this area. Thanks for any help.
