ABSTRACT:
A portable telephone comprises a telephone housing, a connection member having a longitudinal axis attached to said housing and communicating outwardly therefrom, an antenna carried on the connection member, and a pivot system associated with the connection member to permit the antenna to swivel in a plane perpendicular to the longitudinal axis of the outer end of the connection member. Further, a clutch-type system is provided, having first and second bearing faces pressed against each other in sliding, rotary bearing relation for relative movement as the antenna swivels. Finally, a combination of the clutch-type system and the pivot system, allowing for an even greater degree of movement by the antenna, is provided, allowing three dimensional placement of the antenna for optimum reception and transmission of signals.
