Europa-List: Ground plane size for GPS antenna

[Paul McAllister <paul.mcallister@qia.net>]

Hi all,

I am installing a GX60 and I seem to recall a minimum size requirement for the
GPS antenna, however upon scouring the installation manual I can't find a 
reference
to this.  Has anyone out there had experience with installing approach certified
GPS unit and have any recommendations ?

Thanks Paul
