A compression spring, enclosed within a portion of a guide member, provides a bias force to automatically extend an antenna in response to release of the antenna from a retracted position. The portion of the guide member enclosing the spring is nonlinearly aligned with another portion of the guide member that is adapted to receive the antenna when retracted. The retractable antenna assembly solves the awkward requirement for the use of two hands to extend an antenna on portable telecommunication instruments, without increasing the size or significantly adding to the weight of such instruments.
