A method for providing a radio channel list and a mobile terminal supporting the method are disclosed. The mobile terminal includes a radio module for performing a radio channel search and for supporting radio broadcast reception, a radio antenna that serves as an antenna for the radio module, a switch placed between the radio module and the radio module, and a control unit for controlling a process of generating a first channel list of ineffective radio channels by performing radio channel search while the radio antenna is disconnected from the radio module by the switch, generating a second channel list of effective radio channels by performing radio channel search while the radio antenna is connected to the radio module by the switch, creating a valid radio channel list by removing entries of the first channel list from the second channel list, and providing the created valid radio channel list.
