could you explain please how it's possible to connect 3 cards in VDR to 3 LNB's for Hotbird, Sirius, Astra for example with DiSEq-Cswitch
Simple diagram, using quad-lnb's, input of lnbs are called as HB-1, HB-2, HB-3, HB-4 SI-1, SI-2, S1-3, SI-4 AS-1, AS-2, AS-3, AS-4

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.

Hi, there are two versions of lnb's with 4 outputs sold, one with 4 identical outputs to feed 4 seperate receivers, (or diseq-c switches) and one with outputs for hi/V lo/V hi/H and Lo/H ment to feed multiswitches. (like the spaun meintioned in another answer...) so beware which version you by, the purpose is always written down on the box. Christoph
