1. A retractable antenna for a portable communicator including a housing having an antenna mount with a hole, the antenna comprising:

  • an elongated conductor, said elongated conductor being sized to pass through the hole of the antenna mount;

    a protective coating on said elongated conductor;

    an enlarged electrical contact disposed on said elongated conductor; and

    an elongated electrical contact sleeve surrounding and contacting said contact, said contact and said sleeve maintaining electrical contact with each other through spring force exerted on an inner surface of said sleeve by said contact while being movable with each other as the antenna is moved between retracted and extended positions relative to the housing, said contact and said sleeve further being movable relative to each other so that the antenna may be extended further when further extension of the sleeve is prevented and so that the antenna may be retracted further when further retraction of the sleeve is prevented.
