1.2m would seem to be a bit on the small side. Sweden is inside the 41dBW power line, and if the Flysat dish size page are accurate this would suggest nearer a 1.5m dish.
And thats a decent one - not one of the ultra cheap dishes you can get from some suppliers! You will need a circular polarity lnb as well.
If you are inside the 42dBW line you might get away with a 1.2m, but in these fringe reception areas its a case of try it and see.
