I'd be very interested in hearing from others who used the carbon fiber skin without copper paint as a groundplane. I took the stock advice, and did the groundplane, and got good results -- but curious whether that was really necessary. Jack's datapoint, for the xponder antenna at least, indicates it may *not* be necessary.

I also placed the GPS/XM antennas below the eglass turtledeck. The xpdr antenna is the only external antenna which is on the bottom using the carbon fiber as a ground plane with excellent results.
