For the benefit of anybody following this thread I quote from an email I received from Bavarian Satellite. It would be of particular interest to people in Northern Germany experiencing difficulties with BBC reception.
„The CAS75 should be fine in the Hamburg area ( We know people using 60cm standard dishes, which are much inferior). If it has the standard Kathrein Universal LNB mounted on it, then this is a better ( and 10 times the price) LNB .....
You can get adapters to mount standard LNBs on non-standard (e.g. Kathrein) arms.
However if you can`t get Astrad 2D on a CAS75 in Hamburg, then you have another problem_ most likely alignment.....
