Actually they are easier, but they are made for the US market and so the adapter plates are reversed, as are a few other things. You need to drill 2 holes, on the bottom bracket, to get it to fit correctly, but geting these holes, in the right place, is essential as the adjuster, to set the arc up correctly, is limited.
I didn't get to spend much time setting it up correctly, due to the poor summer weather, and other things I had to do, so I've left it as I get near maximum signal on all satellites from 0.8W to 28.2E, which is all I'm currently viewing, in fact, due to limited viewing interest I've rarely moved the dish further than 9E to 19E, except for a feed, on 7E, for a United U21 game.
The adjuster bracket, for setting the arc correctly, is very fiddly and requires a lot of time, and patience, unless you're lucky and manage it first time.
I can still get the extremes of the satellite arc, 42E, 39E, 30W, etc.. but I'm only getting around 50-60% quality instead of 80-90% I expect.
