Hi,
I think the best way actually is to use an Emp Centauri P 168 disecq. It allows 8 lnb !! Here you get more info about this device: __http://www.emp-centauri.cz/pdf/Profi_line_168.pdf
If you want more than 8 sats, you'd better use Spaun switches.
4 X SAR 411F and 1 X SUR 410 will allow you to connect up to16 lnb on your box !!
Happy zapping
