I moved 10 miles down the road and installed my slimline 5 swm dish. Here are my signals: 101 97% 119 0% 99 95% 103 98% All channels that I normally watch seem to be working fine but I keep getting a 771 message and saying guide not downloading in past 10 hours. Why am I getting such good signals on 101,99, and 103 and nothing on 119? Should I tweak dish more? I have a slimline 3 LNB that I can put on there if that will solve the problem. Any suggestions?
