I finally got round to doing some testing around the area with a 1.9Mdish (it's not that easy as you can't just pop it in the back of the van!).

It's obviously still speculation on what will happen but if, as they say, the footprint is idéntical then the results are valid. If there is no signal from 2E then they are even more important. If it has a strong signal here then they are invalid. But at least this gives a picture of the current situation.

So results:
Mora (near Mora Caravans) - very weak signal
Tivissa (lost in the hills somewhere :-) - very weak signal
So for Mora and Tivissa area you will need a 2.4 or 3M dish.

Burgar Valley (between Rasquera and El Perello) K13 - signal on 2 out of 5 transponders and 1 had an occasional lock.
El Perello outskirts, just off KM1108 (L'Ametlla side) - signal on 3 out of 5 transponders.
L'Ampolla - signal on 4 out of 5 transponders.
Tortosa - signal on all 5 transponders.

So for the Burgar, El Perello and L'Ampolla a 1.9 may be sufficient if you are prepared to lose a few channels (and I have no idea which they might be), if not then a 2.4M

For Tortosa a 1.9M should be fine.

From the results I would guess that L'Ametlla will also need a 2.4 or 3M dish.

So, as I suspected, the further north the less signal however I'm suprised at how quickly it has dropped off.
