Hi, does that really work, or am I misunderstanding a quad-LNB? I though the the 4 outputs of a quad LNB are
hi/V lo/V hi/H and Lo/H. Or is that a quattro LNB?
So what you are saying is that a quad LNB can supply any of the 4 "freqs/polarization" down any of its 4 connections?
Any if required the same signal down all 4 connections?

This solution is certainly a lot cheaper because otherwise he would need 12 input lines, so the spaun would not have
worked as it only had 8 Sat input lines. So he would have needed a more expensive model.

Cheers Brian
