    Abstract: A radio antenna interface for a portable radio is provided comprising a radio housing having a control top with a circular walled control top opening for receiving an antenna, the circular walled control top opening having an interior surface with a protruding bumper feature formed thereon. An antenna having has a base portion for insertion into the circular walled control top opening, the base portion has a ring feature forming a full circumference bump around the base portion. Once the antenna is assembled with the portable radio, the ring feature is located beneath and abuts with the protruding bumper to form the radio antenna interface. The radio antenna interface provides increased friction to minimize loosening of the antenna under extreme usage conditions.

    Abstract: A breather valve and a portable communication device including a breather valve are provided. The breather valve includes a housing having a bottom portion having an opening and side portions, a rigid substrate located within the housing and a breathable membrane mounted to the rigid substrate. The breather valve further includes a gasket having a top surface and a bottom surface, and a preloaded compression element across the gasket and the rigid substrate. The gasket has an upper energy director located at the top surface and a lower energy director located at the bottom surface. The preloaded compression element provides at least a first compressive position providing a contact between the lower energy director and the bottom portion of the housing and a second compressive position in which air passes around the lower energy director and the upper energy director.
