Recently I also purchased the FC090CMP (pole mount) and the
SG2100 positioner. Just like the picture, mount the motor pointing downward and slide the antenna mount on the shaft putting a bolt throught the lowwer hole. I hi-lighted the "0" and the "pointer" on the positioner with a sharpie marker to help me see the indicator better. The assembly drawing that came with the dish was the wrong one but I downloaded the proper one. I am using it with a Fortec Lifetime receiver. At 1st I found it confusing to keep the "birds" programmed in the receiver, but it looks like it is working fine now. Good luck! 8)
