I live in a 3 storey town house and it's a nightmare trying to get anyone to install aerials/dishes so thought i'd give it a go myself. I got the ladders out, swapped to a quad LNB and ran another cable into the loft no problem. My next move was to check the signal from the LNB and make sure i hadn't moved thedish at all. The existing box still worked a treat with the existing cable. I then tried the new cable i'd ran connected to the old box...again, worked a treat and no problem. Having proved the signal is still good i then connected the Sky+ box and retired to the tv to tune it in. All of the terrestrial channels are perect but i can't for the life of me tune in Sky+. It appears to be using Channel 68 but i see no picture (just snow/noise) but can just about hear the audio output. In case it was a problem with RF1 out i then tried moving the output to RF2 out but it's still the same. Am i missing something really obvious or does it look like a dicky box?? Thanks for any help guys!!
