technical question re installation of sky+

This is a techie question. I know that when sky+ is upgraded the digibox is upgraded to a new box and an additonal wire needs to be connected between the dish and the box. My friend has something called an "on Q" system which basically means all the tv is pre- piped round the walls etc. Her dish was just wired into a box in her loft and her digibox then plugged into the plug in the wall that connects to the On Q syystem. She now wants sky+. Does anyone know if the additional necessary wire is connected between the dish and whatever is in the loft or will this need to be drilled through the house between the dish and the actual sky+box? Thanks very much. Fairy

i guess it depends whether there is an additional existing cable run between her living room and the loft?

if the distribution box in the loft has 2 inputs, and the same for the wall socket then it could be used. failing that they'll need to run a length of shotgun cable between the dish and the sky+ box.

thanks for this - looks like it is 2 cables then

You will definately still need 2 coax cables from the LNB to the receiver.

If your aim is to have sky+ distributed around the house, the receiver will need to be piped to the distribution box. So you will also need an RF cable from the receiver to the distribution box.

I've managed to do this in the reverse way mine was originally installed. ie I have an aerial socket near the TV. However, this doesnt feed anything (as my aerial is fed direct downstairs). So I have plugged from my sky box to this port and this has fed upstairs. ie its a two way feed. If this can be done, you may have to change the connections on the distribution box (where ever that may be!)

Sorry to be dense but this is too technical for me. The distibution box (at least I think that its what it is) is in the loft and the Sky+ in the lounge. Are you saying that there needs to be 2 wires from the sky+ box into the system or that there needs to be 2 wires from the dish to the distribution box and the the sky+ needs to plug into the one socket? I am a bit confused about the use of the terms €LNB, receiver and distribution box. Thanks very much.

The LNB is the 'bulbous' part on the end of the arm on the satelite dish, it does the 'tuning' in to each channel: for sky+ a twin-LNB is needed, this is so you can record one channel and watch another at the same time. Accordingly, 2 separate wires are needed from the dish to the Sky+ receiver.
The receiver is the white box that sits under the TV
In your friend's set-up, I assume the cable runs from the dish to a distribution box in the loft and then on to the living room. When Sky+ is installed, with it needing 2 separate cables to feed the receiver, one would assume that the distribution box has the option to run more than one cable from the loft to the living room i.e. at least 2 sockets to take the cables from the dish in the loft and at least 2 sockets in the living room to connect to the receiver. If the distribution box does not have this capability, it would probably be necessary to run the 2 cables direct from the dish to the Sky+ receiver - as you say drilled through walls. This is probably a better option anyway, as less breaks/joins in the cable should result in a better signal anyway.

Hope this helps, but feel free to ask again if you need any more clarification!

Even I understand this! I wil check how many sockets they have - she is really not keen about drilling in walls but I think she may have to! Many thanks

BTW - she won't have to do the drilling - the nice Sky man will do all that!

Hopefully Jayhab has explained it now. For sky+ you will need 2 cables from your dish. No need to drill anymore holes - just use the one that is there and have a new twin cable to feed the receiver.
