I live in Wisconsin,so far this month we have over 30" of snow.I haven't lost signal yet! Nor did I lose it all last winter! I do lose it at the start of a rainstom however.It only goes out at the very start,and lasts about 5-10 minutes.I have 2 dishes for 110,119,129 and the wing 61.5. Today they are covered with snow,but picture is fine!
