Patent ID: 7747233

Claim:
An apparatus for selecting an antenna in a digital broadcast receiving terminal, the apparatus comprising: at least one fixed internal antenna; at least one external antenna which is detachably assembled on an outside of the digital broadcast receiving terminal; a signal-receiving condition sensing unit for sensing a signal-receiving condition for a digital broadcast signal input from the internal antenna and the external antenna; and a controller for periodically comparing sensing results of the internal antenna and the external antenna with predetermined thresholds according to a predetermined test period and informing a user that the internal antenna is capable of being used even though the external antenna is capable according to the comparing result, wherein, if the signal-receiving condition for the digital broadcast signal improves for a predetermined length of time, the controller reduces the predetermined test period and if the signal-receiving condition for the digital broadcast signal worsens for the predetermined length of time, the controller increases the predetermined test period.
