Like other people I can give half ass answers. I choose not to do that. As a way to cover all the bases I suggest a Winegard HD7082P All Channel antenna with a Winegard AP8275 preamp and a ChannelMaster CM9521A rotator. The HD7082P is the strongest consumer grade all channel antenna to hold up to the rough winters at your location. . Commercial grade antennas are available , the price is high .
