Might be OK to get Canal +, but with only a 39 cm dish, Sky would be a bit dodgy. I was in the Loire (and before any comments, the region not the river) a couple years ago with a 90cm dish, and couldn't get Motors TV. Mind you, by the time I'd got the rest of the caravan set up in the hot sun, I didn't spend too long on adjusting the dish - kept hearing the call of a cold beer...
