I have never been satisfied with the way the DMX741 LNB fit into the scaler ring. It always seems to wobble around and did not have a good fit; even by tightening down the set screw. I found that by inserting a small piece of rubber between the DMX741 LNB and the scaler ring it made for a tighter fit.
I found an old rubber gasket that is about 3/16 inch in diameter and cut a piece off about 1 inch long. I set this into the scaler ring near the set screw, and then slide the LNB down into position. (see picture). I have been running this on one of my C Band dishes for over a year and the rubber has held up without breaking down.
