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.

Radio antenna interface

A control switch () is provided to facilitate a primary user interface for a control top surface () of a non-orthogonal control top () of a portable communication device (). The control switch () comprises a thumb button actuator (), a rotary lever () having a lever arm () extending therefrom, a transfer arm () coupled between the thumb button actuator and the lever arm of the rotary lever, and an electrical rotary switch () with a switch shaft () providing a primary axis of orthogonal rotation. Actuation of the thumb button actuator () results in linear, non-orthogonal motion of the transfer arm () being translated into rotary motion of the switch shaft () about the primary axis of orthogonal rotation ().
