How to use sky on a caravan

Hi everyone, I have a caravan that I use quite a lot during March to November and I have noticed others that have a sky satelite dish on them and wondered just what I need to receive sky while staying in my caravan. Can you advise me please? Do I need to take my sky card with me or can I just use a sky box for the free channels?

You need to take the card with you or apply to Sky for a free view card. (they will charge)
You will also need some tackle to install and point the dish at the satellite.

Thanks a lot for the advice
