Ils 28
was installed due to many complaints that whenever the weather was bad, or at night the Germans would not permit the overflights on the other ILS runways.
So traffic was forced to land on 28.
Thus the ILS was installed.
But to call it UNCAT is a new one on me, so can we see a rash of UNCAT ILS's. Most ILS's in smaller Swiss airports have several complications, so perhaps they should introduce a new cat "Cat 0".
