You can use 6 LNB and
- an diseqc 8/1
or
- 1 diseqc Spaun sur221f and two Spaun sar411f
You must choose in the receiver diseqc on "diseqc 1.1"
an you have the choose between sat 1, sat 2,... => sat 8 or sat A, sat B,... => sat H
But with this method, i' not sure you can have quad pip or multichannel channels streaming on PC.
The LNB unicable can only send the differents channels who are in the same sat.
