I mounted mine out there, but leveled it with washers on the mounting bolts
using a digital level. Works great.

Bruce,
Yes, the antenna needs a ground plane but it doesnt have to be the whole airplane.
On my Skybolt I cut an aluminum disc, around 8 diameter but its been
a long while, and glued it to the inside of the fabric and attached the antenna
to it. Worked great. Probably some better answers out there if you do a Google
search.
Good luck on your non-RV-10 ;)

Does the antenna need an aluminum ground plane? If so, how big? This is a fabric
plane, similar to a Champ.

Just think of how much of a 'ground plane' a handheld has.
A metal wing intersection fairing works well on my Pitts with the rubber
ducky attached to the end of the coax.

On my fabric covered Rans S6-Es I made a 12" square Aluminum plate to mount the
bent whip antenna. It's worked great.

Bruce,
I=99m not familiar with this radio but I assume it is GPS only, no
comm. If so, the GPS antenna needs no ground plane. Whatever bracket
you can fabricate is fine. This is why they work when mounted on top of
fiberglass.
For what it=99s worth, standard =C2=BC wavelength aircraft comm
antennas do need a ground plane. The radius of the ground plane needs
to also be at least =C2=BC wavelength. At 120MHZ this works out to be
24=9D or so. Conventionally this is provided by the skin of the
airplane. For composites you can add four or so strips of copper tape
on the inside of the fuselage, the ends connected to the base of the
antenna. You can also run four or more light wires to the base of the
antenna spread out like the spooks on a wheel.
As previous suggested however, for a tube and fabric aircraft mounting
the comm antenna to the frame at any point will provide the needed
ground plane =93 no other action is needed.

For what it is worth, Garmin does require a ground plane for its
Certified GPS antennas. Why, I do not know. I did small aluminum plate
on my RV-10, then added some aluminum tape to extend it where flat plate
would be difficult.
