If I cancel my Sky subscription can i add more recievers to recieve free channel
Yes you can. Your expired subscription card will act like a FreesatfromSky (fSfS)
card for your existing box. If you want to use the Quad-LNB output to drive
other boxes, Sky will let you buy up to four of their ÃÂ£20 FreesatfromSky (fSfS)
cards, but these are only needed for getting the right BBC and ITV regions
and access to Channel 4, five and Sky Three.
Do I understand you in saying if I'm not bothered about which region I watch then it will not matter. will it be as sky is now where we will be able to choose which BBC region we watch we watch?
Without a card, the Sky Digibox will provide the London BBC and ITV regions. With a card the "correct" BBC and ITV region is show. You can select other BBC regions and ITV regions in the normal way with or without a card.
