It is not possible to plug an aerial into a Sky Digibox to receive Freeview channels because the boxes have not been designed this way.
You will continue to get the full Sky EPG listings; you just will not be able to watch subscription channels.
If you have an HD-Ready TV and a standard Sky box, this is a good option.
Does your sky box still work without subscription?
I have a Sky+ box that is only used for recording. When you cancel your subscription your Sky+ box will still work and using your now deactivated viewing card you will still be able to receive a handful of unencrypted free-to-view (FTV) channels, including BBC1, 2, ITV1, C4 and C5.
Can I use Sky dish for Freeview TV?
Yes you can, a working satellite dish will be able to receive Freeview via Satellite when used in conjunction with an approved Freeview Satellite Digital Receiver or Recorder. Note that the LNB (Low Noise Blocker, which is round or oval and sits in front of your dish) may need to be replaced / adjusted.
Are old sky boxes any use?
Your old Sky box will still work as a Freesat from Sky box to receive free channels on it, but you won’t be able to pause, record or watch any old recordings on the box anymore. Alternately you can give it to friends or family who want a Freesat box, or sell it on eBay (don’t expect to get much for it).
Can I use my Sky card in another box?
Your Sky viewing card is linked to your account and allows your Sky box to access your subscription channels. To use your viewing card, it must be activated and paired with your Sky box, even if it’s an old card you previously used for another box.
