PURPOSE: An external antenna device capable of outputting a high quality broadcast signal is provided to facilitate a signal processing by minimizing all kinds of the noise flowing in a broadcast signal. CONSTITUTION: In an external antenna device, an antenna unit receives a signal. A LNA unit is directly connected to the antenna unit and lows noise-amplifies the received signal. An interface unit transfers the amplified signal to the connector of a mobile communications terminal(200) and supplies power to the LNA unit. |
