can anyone please tell me how to get sky in another room please we have extra box and card ,thankyou in advance

you need a multi lnb on your dish to run 2 boxes.Lnb's are pretty much a simple job to change although im not sure if you might need to change the dish too.
The other way is to run a cable from rf2 from the rear of your existing box to the room you want it in with a sky link(remote eye)and the channels can be turned over from that room.

It sounds like you're after a multiroom subscription - Ring sky, £10 pm, plus any install fee. If you fit all the cables yourself, you just need the subscription.
