hi
i have had good results using either LNB INVACOM QUAD 0,3 dB (4 individual exits) or the LNB MAXIMUM QUAD 0.2 dB (4 individual exits), and i have seen invertos quads performing ok on offsets (they are designed primarily for offsets but some installers use them on prime focus dishes also - but found they perform less well on a prime focus dish than an Invacom - maybe they use them as the Invertos are cheaper for them to buy!)
some people have tried to put the prime focus c120 invacoms on a offset CM but with varying reports of their effectivness!
hope thiis helps
