Need to get the antenna up high on the roof , no trees in the way of reception. A tripod antenna mount is the best. I suggest a Winegard HD 7082P Tv antenna and a Winegard Preamp AP 8700. Go to the >>START Maps<< part of tvfool. Move the antenna from UHF 31 to UHF 44 and points in between to see which group of channels come in the best 31,34,40,36,38,10,51 or 44,38,10,51,34,40,36. . . . Channel 5 to the south may very well come in on the back side of the antenna , it is a strong signal at your location.
