I know that the satellite tv dish must be in an area where it gets clear access to the satellite, but what happens after a big ice storm or heavy snow?

The dish must be fastened SECURELY, to avoid the wind from moving it, and with a CLEAR VIEW (no trees, and approx. 45deg angle) toward’s the equator, as that will lose your signal too.

The signal is “lost” when bad weather comes along. Ice, snow, and thunderstorms (with lightning), block it out, but after it clears out, the signal resumes.

Note; if you are worried about ice and snow, there are heaters available to eliminate these problems. You will have to contact a dish service to find out more information.
