Winterizing my DirecTV Dish



Does anyone here ever have problem with frost and ice on their dish during the winter time? I have a 5 LNB dish and always find it to be a pain when I have to clean it because A. the ice just doesn't want to come off and B. it's cold outside and the less time I have to spend out there, the better.

What can I do to keep ice from sticking? Is there a spray or anti-stick oil I can use?
