The most common UV additive used in coatings is micro fine TiO2. There are some organics out there but they only perform well in conjunction with TiO2. The oxidation of the metal molecule removes the dipole capacity of the metal and it behaves less like a metal and more like an inert compound. Most coatings with UV resistance should not interfere with antenna reception.

I put my comm and nav antennas inside the fuselage. I am using an ICOM handheld attached to the instrument panel with Velcro. I am able to monitor aircraft in the traffice pattern 125 miles away when flying at 2,000 agl. I have had consistent communications with the tower from 20 miles out (that's 20 minutes of flying time in the Renegade). I believe that you will find that the uv coatings are not metallic, but an inorganic material.
