[aprssig] sunroof antenna?

[KC2MMi]

Just FWIW, here in the US, in the auto industry, "sunroof" refers to a metal
plate and "moonroof" refers to a glass or plastic plate in the roof. A "glass
sunroof" is by definition a moonroof, not a sunroof at all.

The on-glass capacitive antenna systems are all designed for a specific
thickness of glass, you might want to check that out because the odds are Murphy
has been there and that the moonroof is a different thickness from the
windshields and side windows.
