A coating composition, comprising a film-forming component, a radiation curable group, and a matting agent, wherein, when the composition is deposited and treated to form a cured coating, the cured coating is characterized as having a higher concentration of the matting agent in a top half of the coating relative to a bottom half of the coating. In one aspect of the invention, material is removed from the substrate assembly by pressing the substrate assembly against a planarizing surface of a planarizing pad and moving the substrate assembly across the planarizing surface through a planarizing zone. The receiver then determines a gain setting of the receiver with the antenna on.
