Well...
I doubt that the signals from Galaxy 10R can penetrate glass; I've heard of people getting DirecTV and DishNetwork signals through windows but never for Free-to-Air -- which is what you want.
Second; for your area the dish must point at around 226 degrees on the compass -- that's South West. Your window is 80 cm wide and that is the minimum dish size needed for Free-to-Air reception -- so it would be real difficult to aim that dish SW if your window faces south; there just isn't enough of an opening for good signal reception.
This is just my opinion; perhaps others have experience with inside mounting.
