I changed my LNBF on my six footer from a Bcs 621 to a c-2 from Sat Av.What a difference! All my quality readings on the 922 jumped up 10 to 20 points across the board. Now my questions. I hopped on the Mercury II deal from Sat AV and the box works great on the new dual cband lnbf,but all my channels are showing opposite polarities on the mercII from what Lygnsat shows. The DSR 922 is working great with the LNBF set to standard and not rotated 90 degrees.Do I have the lnbf 180 degrees out? I have not fine tuned it yet but before I do I would like to know if I am 180 out or what. Also Channel Master does not seem to support the M2 is this true?
