Digital broadcast is in the UHF band, which is line of sight limited. The curvature of the earth pretty much limits the range, so up here probably no more than 70-90 miles. The old VHF broadcast would ‘bounce’ signal off atmospheric layers, so we were able to pick up Sacramento and some San Francisco stations with a rooftop antenna, especially the low VHF channels 2-6.
since all the stations have gone to digital broadcast, with reduced transmission range, I doubt you could get any signal up here even with a rooftop antenna
