I suggest a Winegard HD7694P antenna with a Winegard HDP269 preamp aimed at 220 true - 227 degree magnetic compass to start with. Then turn the antenna to the left and right to get the best reception of the weaker channels like , WSOC-TV 46 , WMYT-DT 39 , WTVI 11 , WXAN-DT 50 and then tighten the antenna in place. I suggest replacing the outside coax cable that was connected to the old antenna. With new RG-6 coax. Here is how to aim Tv antennas ,
