I have a 722 and 222 with a 1000.4 dish. I have alot of trees so the dish is about 200 feet from the receivers. Everything was working fine, now I have a recurring problem. Both receivers loose signal at the same time. Tech came out and got it working and the in the morning lost signal again. Tech came out again and changed LNB and it worked fine that day. The next morning it quit again. When I check switch it counts 1 of 38. Tech came out again and checked all connections and got it working again. Now got up this morning and it is not working again. Could the distance from the dish be the problem? My signal strength is ok and I can't understand why it worked fine for awhile and now I am having this problem all the time. Help!!!
