I've had Dish Network for almost 10 years and I've never had it go out except for when solar flares interrupt the signal.
The great thing about satellite TV is that the signal comes directly from the satellite (duh!) and does not have to go go through a processing site like cable does. No physical cable lines or power lines (except for electricity) bringing it to your house that can get damaged or severed. No lines to power poles or running underground. Just beams in directly from the satellite in the sky to your house (cabin/lodge/boat/RV, et al).
