Went to my local Best Buy to get an indoor antenna as a back-up to DTV which seems to go out all the time when it rains or snows. TV guy there told me to spray the dish with Rain X because the picture goes out because of rain or snow collecting on the dish. Anyone ever hear of this? The Rain X said not to use under 40 degrees so that lets today out ,plus its starting to snow. I'm this way and that about this ,anybody ever try it?
