ABSTRACT:
An antenna configuration for a portable radio set provides a helical antenna, a rod antenna and an antenna connecting device that selectively connects the two antennas to a printed substrate to enable their operation. When the rod antenna is partially retracted within the interior of a body housing beyond a threshold point where the antenna connecting device becomes electrically disengaged from the rod antenna, the antenna connecting device elastically returns to an original position and becomes electrically connected to the helical antenna. Alternatively, when the rod antenna is fully extended from the body housing, the antenna connecting device is electrically connected to the rod antenna. The present invention provides advantages in that a large amount of radiating power may be distributed in accordance with the length of the rod antenna, thereby minimizing any radiating interference caused by a user's body and reducing the loss of radiating power.
