Ice has never been a problem for me (have had satellite TV since 97 and have had satellite internet for a year). Snow on the other hand can and does build up and cause problems for me. If dish is on ground it is fairly easy, just swipe snow off. Ice, if it does cause a problem--don't know if we'll even be watching TV, electric might be out lol--would be like cleaning windshield on car, perhaps gently so that you don't knock it out of alignment, even if you know how to get it back, it can be a headache outside in freezing temps.
P.S. I'm in the eye so to speak too, here in Oklahoma. Predicted for 1-2" in my area.
