Just remember, with several inches of snow on your roof, the quality of your digital reception will go down. Just another hint to get your antenna outdoors and some 25-35 feet above ground level. There is no substitute for a good directional antenna mounted outdoors if you want top reception and no 'dropouts' or 'blocking' on your display. I would say this, generally, holds true for a distance of anything over 25 miles from antenna location to the transmitters. Of course, I am the first to admit, every reception situation is different.
