Abstract (en)
The antenna control apparatus of the present invention receives a radio signal from an antenna, the reception level decision section decides the reception level of this received signal and the control section controls the driving section so that an optimal antenna length is obtained according to the decision result. This allows the antenna control apparatus of the present invention to automatically extend/contract the antenna to an optimal length without intervention by the user. <IMAGE>
