Thanks a lot for your help.
I set the LO correctly. I can verify that since I get over 90% quality bar with the circular LNB mounted at the LNB bracket.
I use a
SG2100 rotor. I just tried to mimic
Sadoun's sample
installation with SG2100 and Fortec Lifetime.
I wanted to get music channels on Nimq1 with the circular LNB.
If I use the Fortec LNB only, I can get all FTA programs on all viewable satllites. If I use the DBS circular LNB only, I can get music channels on Nimq1. So they all work well.
The problem is how to make both of them work side by side (of course not at the same time). I know how to use a switch. I don't know how to tackle the angle offset problem.
I think what you said about the angle offset is totally true. When my dish points to Nimq1, I can get a quality bar only when I put the DBS LNB directly in front of the linear LNB on the bracket.
One solution may be like this: I will change the longitude of Nimq1 stored in my Fortec receiver to compensate the 4 degree angle offset. So the dish won't point to Nimq1 but the Circular LNB will point to Nimq1.
Will that work?
