I need your help identifying what material my mushroom panel is made of. It's from a DG-202. Given the age, I'm assuming it is painted fiberglass. But the black pigment runs deep - as if it is really carbon. I'm asking because I'm considering putting the GPS antenna puck under the panel. But if it is carbon, I need to mount it externally. I'm not sure if this is the stock mushroom panel.

The pod and panel are fiberglass with thick paint, and I have mounted antennas underneath with no obvious issues. But, I preferred to mount puck style antennas either on top of the pod, or on a bracket at the top front, well clear of the compass (if mounted on top), and run the cable through a hole in the front of the pod. Just because it is fiberglass and paint doesn't mean it would attenuate the signal to some (small) extent...
