Node in attic as high as possible on top a stack of plastic boxes. The house happens to be at a relatively high point of the city. The node is under the tiled roof which has thick wooden boards and clay tiles. I thought it was interesting to see how being under the roof seems not to cause a problem.

Using https://www.heywhatsthat.com/ and the height of the attic one gets a plot (red points) of theoretical coverage as shown:
which in practice seems to hold true. A map of confirmed coverage of the Munich mesh which includes this node and at least two other high nodes is available here Meshtastic Munich good locations - Google My Maps.
Happy to see any comments concerning build improvements and traceroute examples from the Munich area. Servus!
