ABSTRACT:
An antenna device includes a first antenna capable of moving between a storage position where the first antenna is contained within an equipment housing and an extended position where the first antenna is pulled out of the device housing for receiving and/or transmitting a signal. A second antenna is attached to the tip of the first antenna for receiving and/or transmitting a signal when the first antenna assumes the storage position. The rotator rotates the first antenna with respect to the device housing in the extended position.
