[QUOTE="fancyabrew, post: 968351, member: 408356"] grrrrrrrr. I was meant to be having Q installed today but is all gone horribly wrong! Before I explain, I can't fault the Sky installer AT ALL he was really good and spent about 3 hours trying to get it to work! Anyway the problem seems to be with the 2nd LNB on the new Wideband LNB feed that SkyQ uses, the 1st works totally fine, the second gets NO signal, only power. Just to add I've got SkyHD and that works totally fine and with a decent signal (old non wideband LNB obviously). First thought was the cable (my cables goes to a distribution box just to confuse things). But we tested the cable BEFORE the distribution box to rule that out and it fails! Laid new cable, fails, various LNB's fails. BUT running the installers tester directly attached to the LNB WORKS! Attach a 2m length of cable to the LNB and test from that FAILS! So rebooked with a team leader SkyQ expert next Sunday. Installer never seen anything like this before. And I must admit being in IT myself and knowing a little bit signals going down cables it is all VERY weird! Anyone who knows anything about Satellite have any ideas!? The village has a TV relay + mobile dishes on the mast very close to the LOS, could it be some interference only effecting wideband (as normal Sky works fine) from this? If so we're probably snookered! Not sure if its the Horizontal or Vertical polarisation that's got the issue, not really sure if Sky splits the polarisation ie LNB output 1 is one polarisation and the 2nd the other. [/QUOTE]
