You might want to get a good bow-tie or even a yagi setup in your attic or outdoor. Even-though it says 1 edge, you might be getting some multi path issues. If multi path is an issue, a good yagi may resolve it. Usually multi-path rarely an issue with digital, but it can still cause signal quality issues. Have you tried a good pair of rabbit-ears?

I have an HDHomerun Extend so I can set a channel and move the direction of antenna around to see what get's me the best signal. With 1 edge, it might not be coming from what TV fool says (even-though the TV broadcast tower is exactly that direction)
