Yeah you can connect your TV to your satellite dish (via a decoder such as a SkyHD or a Freeview box) to continue to receive UK TV. That’s exactly what we did when we first arrived. You’ll just need to point your satellite dish in a slightly different direction. This thread has all the details you need.
Sadly iPlayer and Sky’s catch-up doesn’t work as they see from your IP address that you’re not based in the UK.
