Abstract:
An extendible whip antenna assembly comprising:a helical antenna adapted to be mounted on an outside surface of a housing; a whip antenna extending through an inside of the helical antenna, said whip antenna being slidably movable between (i) a retracted position in which the whip antenna is retracted into the housing, and (ii) an extended position in which the whip antenna projects from the helical antenna beyond the outside surface of the housing; a holder made of an electrically conductive material, said holder being adapted to be electrically connected to a transceiver circuit within the housing and to fix the helical antenna to the housing; and a stopper made of an elastic electrically conductive material, said stopper being coupled to a proximal end of the whip antenna and said stopper including lateral projections for abutting against an external abutment end of the holder when the whip antenna is in the extended position so as to secure the whip antenna to the housing when the whip antenna is in the extended position; wherein the stopper comprises at least one axial slit extending from a first end of the stopper.
