[QUOTE="Terryl, post: 958712, member: 369937"] We in broadcasting have tried everything known to stop rain/snow/ice fade, the only thing that worked were bigger dishes, a total enclosure for the dish to keep the snow/ice off (radomes) or heated dishes and LNB's. The bigger dish was the best solution, and putting something like furniture polish or car wax on the dish/LNB eye did nothing but collect dirt and make things tougher for the jr engineer that had to go out and clean them off. You have several tons of water vapor or ice crystals in those dark clouds between you and the dish, how can you keep that off the dish/LNB? At cable TV head ends you will see some very big dishes, these are to prevent rain/snow fade outs. One solution for a small dish that worked good for rain and snow was a black leaf trash bag slipped over the dish and taped off with duct tape, made a very effective radome. For snow and ice problems a 40 watt light bulb in a drop light was inserted up into the bag and strapped to the dish LNB arm (out of the way of the LNB eye) then a heat tape thermostat can be used to turn it on (and off) when it gets to freezing.
