A noise margin of 5db is doable in some cases, but it is so close to the digital cliff, reliability is unpredictable. As John pointed out, you have an adjacent channel issue with a much stronger RF 51 in the same direction which isn't helping either. I personally find about a 1-3 db noise margin as the drop off point for an un-amplified 91XG.
