A hermetically sealed mobile antenna base containing all of the components necessary to proper antenna functioning with the exception of the loading coil and antenna whip for vehicular application is disclosed. A single connector screw extends outwardly from the base casting and is insulated therefrom by an insulating washer. Interiorly of the base casting an impedance matching capacitor is disposed with one lead connected to the connector screw and the other lead connected to ground. The coaxial cable is led into the base casting and has its center conductor connected to the connecting screw and its ground conductor connected to the casting. The complete interior of the base casting is encapsulated with an epoxy compound. Spaced apart connection ears extend from one side of the base casting providing for attachment of the antenna base to the vehicle.
