Since aluminum is non magnetic, I would assume a mag-mount vertical
would
not couple properly to a aluminum ground plane.

Thoughts ?

CL -- I doubt, therefore I might be !

I tried this on a 2M antenna and it didnt work so well. My theory was that
since the antenna was not firmly attached to the Al then the capacitve
coupling between the base of the antenna and the Al groundplane was off.
Fixed the problem by soldering radials to a coffee can lid and placing the
antenna on this.



Aluminum is a decent conductor and as a result, it will work. Possibly, the
Lack of the magnetic attractive force was not pulling the magnet very close
or firmly to the plate. This could be helped by putting something on the
bottom of the aluminum / aluminium to get some force and closer spacing,
such as another magnet. You can also generate a lot of posts / re-posts on
the operating theory of mag mount antennas and what this capacitance does...
