Copenhagen do have a very weak signal as stated in the answer above. I don't think we have enough information about the Freesat boxes yet. There is a very big difference in the tuner in the Skyboxes. Some tuners can't get any signal from Astra 2D in your area (or where I live in central Sweden). The most sensitive tuner was the Pace 2600c1 where all channels come in 24/7 for me.
The signal strength is a bit weaker in Copenhagen than where I live. You could possible get away with the Gibertiny 150 but that will leave you with no weather reserve whatsoever. I doubt also if you could get both the channels with vertical and horizontal polarization (vertical is weaker). The Channel Master 180 would be a better choice but also a bit more expensive. If you don't know anybody that have succeeded to get freesat in Denmark I would suggest the Pace 2600c1 or the 430 (you can get them from
Ebay
with a working card which would give you the same channels as freesat). Also very important is a good LNB. Invacom quad (QDF-031) or as some treads have suggested the cheaper but stated better maximum LNB
