I have mine installed but have not used it yet. I think you are going to be
much
better off with a vertical dipole in the Europa than a ground plane. The Archer
antenna the others spoke about is a vertical dipole. Mine is fastened to
a piece of balsa wood that is fitted to the contour of the fuselage on the port
side as far aft as possible. It is just about opposite the inspection port
in the root of the rudder. I'll let you know how it works in a year or so.
