It's a normal patch antenna, bought together with gps addon card:

After all your tips I just checked whether the roof itself blocks the
signal or not. I put the patch antenna together with a metal disk on top of
a high wardrobe, close to ceiling, and I guess it is the best position
here. See attached screenshots.

I didn't have to stick to "good enough", David :)

Unfortunately, I will have to move this ntp server to another location (or
make another one and leave this one here). It will not have access to south
facing window there, only west is possible.
