Antenna systems for use with wireless communicators, such as radiotelephones, are provided and include a first antenna configured to be internally mounted within a wireless communicator and a retractable, second antenna that couples with the first antenna when extended. The internal, first antenna is resonant within one or more frequency bands and the retractable, second antenna couples with the internal, first antenna so as to enhance one or more of the resonant frequency bands of the internal, first antenna.
