I've had DirecTV for a year. I forgot what they told me my exact signal strength was when they installed it, but it's in the high 90% range. I've only lost signal when a very strong T-storm cell is directly in line with the receiver. Twice in a year, I believe, and for just minutes. Snow doesn't seem to bother it.
Only negative is that I don't get the Providence channels, and I don't get the local conditions portion of the Weather Channel broadcasts.
I also don't get Bourne's local access channel, but I can live without the live feed of the Selectmen's meetings
