A pretty clear show off of what hi-rise can do to your reception when you live in a city center (Groningen, NL). Not much from the west up to the north / over the North Sea and parts in the east.
Official FA antenna is on the third floor (in Dutch: tweede verdieping) outside, I’ve configured tar1090 with PTRACKS=24.
Rings at 100,150 and 200NM.

I occasionally go beyond 200NM, for example in northern Denmark and around Frankfurt, Germany.
