Abstract: An article transparent to radiofrequency (RF) signals includes a substrate and a coating arrangement on the substrate. The coating arrangement includes a primer applied to and in physical contact with the substrate, a topcoat applied to and in physical contact with the primer layer, the topcoat including an organic polymer material, and nanoparticles dispersed throughout one of the primer and the topcoat. A content of the nanoparticles ranges from 0.1 wt % to 10 wt %.
