VU+ Duo receiving no signal

[adm]

Yes that was a typo I meant to say I disconnected all other outputs. I have tried 3 different cables and I looked up how to wire an F connector and did it to the letter. I have also done them in the past in my previous house and they always worked fine. We even tried a bit of cable that they weren't using anymore that was previously working in their house.
I tried another sky box from my own house and that didn't work either. The switch in the loft space sounds likely. Can I do something to recreate that in my flat?

On second thoughts: If there was a muti-switch in the loft space 4 of the LNB outputs would be connected to it. Were there 4 connections from the LNB going to the loft?

If there is a switch in the loft space there are probably spare outputs on that - you could connect your single cable to a spare switch output. If you are lucky there could be more than two spare outputs on the switch.

Yes all 4 were going into the house but I still haven't asked the owner whether there's a switch in the loft or not. Why won't it work by just taking a cable straight from the dish?

Traditional universal LNBs have 4 modes of operation which your box controls by sending a control signal back up the connecting cable [High voltage, low voltage, tone and no tone].

If it is a Quatro LNB then these 4 modes of operation are fixed in the LNB and each mode of operation is available as a separate output - hence requiring 4 outputs. These 4 signals then go to a multi-output switch where the individual outputs of the switch are controlled by the boxes connected to them. It was a way of distributing a satellite signal to more than 4 tuners but without having to have more than 4 LNB outputs.

If you directly hi-jack one of the outputs from a Quatro LNB at best you would only be able to get the signals associated with that mode of operation (possible a quarter of the channels if you were lucky) BUT you would also deprive your friend of those channels.

Bear in mind that this is still speculation until you can confirm what is, or what isn't, in the loft

Recent technology advances can achieve distribution in a different way but as you say the dish/LNB was installed in 2011(ish) so its not new technology.

It's not Q the OP answered that earlier and all channels were found in one location.

The location that work is presumablly one served from the switch.

What is being described above isn't Sky Q. Its based on technology that's been around for a decade or more. The OP doesn't know how the cables are connected in the loft, or to what.
All channels could be found in the original house if a Quatro LNB and a muti-switch is used. What would break this set-up would be to remove one of the inputs to the switch and route it to an adjoining property.

unsure about the switch theory but are there any other sat dishes on property as i have 2 fixed and motorised in conjunction with a 4 way switch?

duo should work on cable direct from lnb to box and have you checked in tuner for a signal on another sat as it is getting common now to move dish to a better sat.

I'll probably just put up a new dish for my property as it's too much hassle for myself and the owner to be digging in their loft honestly. Thanks for your help guys

I just want to give an update on this. I got a guy out and I told him everything I did and he went up to the dish and had a look at the f-connector that I had prepared and did it again himself which then sorted the problem!
He said a little bit of the wire was exposed and that it was touching another cable coming from the dish going into the main house.
Thanks for your help guys.

Didn't you say that you had tried more than one cable?

Yes I tried 2 other different cables but they both had the little bit of wire coming out. He said it was 2 strands that were touching the other cable.
