I'm just about to install a second lead to from my Pace 3100 to my existing dish to enable the complete sky+ package. I read somewher on this site that Sky install twin LNB's as standard. Does this mean that i can simply run a second ariel lead to the dish to get the system working or do i need a quad LNB. Can anyone explain as I'm a little confused to say the least.I've no interest in multi-room if this makes a difference. Thanks in advance!
