Last week, Directv came out and realigned my dish. It's a Slimline 5 lnb, connected to a WB616. I was having rain fade problems. The signals went from the 50s to the 80s-90s (on 99/103) by adjusing the scew. 101/110/119 were/are fine in the mid 90s. So, I thought my problems were resolved. However, it rained this week, and each time it rained, 99/103 would go out. Singal strength below 40. Yet, 101, 110, 119 remained in the high 70s low 80s during rain (mid 90s without rain) Any thoughts on why 99/103 is so impacted, while 101, 110, 119 seem more stable?
