I live in northwestern Indiana, and I loose my signal on some or all satellites when it rains. Is this normal, what should my signals strength be? I know rain fade is common, but it is hardly raining and I have lost 119. And when it goes out, it just goes away, right now 110 is in the mid 70's, but 119 is 0? I have a dish 500 and it says dpp twin lnb's and a 625 as well as a 301.
