Without a HD reciever you only need single lnb for 91.Your probably gonna be 10deg. lower, an eight of a turn to the left, lean into it hard with some skew.Set your reciever to signal beep.Turn your tv volume up al the way. Get on the roof bump left or right up or down for highest pitch beep.Then confirm that nimiq1 is showing as sat recieved then channel scan. Done.
