I inherited a 1000.4 WA dish with 722 reciever. Theres a dp34 switch and 2 coaxes in & 2 coaxes out, no diplexers etc on the cables. Signal strength seems to change in morning & evening. On TV #1, only receive from 110 & both TVs lose signal easily. I have Satlink WS 6906 and am lost on how to use it. Should I use settings for 119 only or I have seen settings for 110 & 119? Please help.
