No experimental evidence--just theoretical. I recently purchased a MR that came with the Naza GPS and this mount w/ copper. I removed the copper from it, though. I like the mount, otherwise.

The copper is a partial Faraday cage around the receiver, and GPS signals come in from angles as low as the horizon. Some of those signals will be blocked by the surrounding copper on the sides. As to how much this will affect real-world performance of the GPS, I don't know. But I don't see it helping. Since GPS operates in the 1.2-1.6GHz range, you're not going to get any interference from 2.4GHz radios, and the engine noise is very low frequency compared to the GPS so it's not going to cause any problems either.
