Using Sky abroad is a violation of their Ts & Cs. However, I understand that lots of people do it. The Astra satellite signal becomes more oblique as you go further south, so I believe a one metre dish is required below a certain latitude, instead of the mini dish used here. Don't have the details but I'm sure they can be Googled. The UK Freesat channels can no longer be received much beyond the UK due to being moved to a narrow spotbeam on the Astra constellation, but as far as I know Sky is still available.
