If the dish is prime focus this will be the problem. Using a LNBF ( all in one ) on a prime focus dish will result in severe signal loss. If you're using a universal C120 LNB (one that bolts onto a feed that came with the dish) then the cause is probably incorrect skew (rotation of the LNB).
Using an Invacom with an adjustable feedhorn should do it. It's a bit late now, and sorry to say it, but the quad ( QDF-031 ) performs better on 2D than the single version you have ordered.
