<P>PROBLEM TO BE SOLVED: To provide a mobile radio device that attains high reception performance, by improving the antenna gain deterioration due to electromagnetic field coupling among a plurality of antennas. Ž<P>SOLUTION: The mobile radio device includes a first antenna 11, a second antenna 13, a first low-noise amplifier 12 connected to the second antenna 11, a second low-noise amplifier 14 connected to the second antenna 13, and a DTV tuner module 15, enabling combining diversification which is connected to the first low-noise amplifier 12 and second low noise amplifier 14. In the using frequency band of the DTV tuner module 15, enabling the combining diversification, input impedances of the first low-noise amplifier 12 and those of the second low-noise amplifier 14 are all different.
