[20230125] Inspection

As can be seen from the pictures above, quite some rust has accumulated on some of the bolts. More importantly, I’m no longer trusting the mechanical stability of the chimney that much. So in Summer 2023, I should spend some time on fixing this, or construct a new antenna mount altogether.
