A reflector antenna feed RF seal between an antenna base, a feed hub and a vertex plate. The RF seal formed via a generally annular gasket of compressible material adapted to seat around an outer diameter of the feed hub. The gasket having an outer diameter greater than a diameter of a joint between the feed hub and the antenna base and less than an outer diameter of the vertex plate. The gasket compressed within a cavity formed between the antenna base, the feed hub and the vertex plate as the feed hub is seated within the antenna base. |
