Sky Cards & Subscription
The sky system is one of the best in the world with all the easy to use menus & functions it just can not be beaten
This system requires a satellite dish minimum 1.2m for most of the pay per view eg sports etc the free to view could be a different matter depending on location
There are certain disadvantages particularly if you are using this abroad because you lose some of the best functions they being Iplayer and sky anytime you also lose the function of remote recording and it can be expensive with the full package too
good news is you can get most of the functions back with a VPN even if you live abroad More info on VPN here
