PROBLEM TO BE SOLVED: To provide an antenna system capable of realizing the best reception state at all times independently of an arrival direction of a radio wave and a reception characteristic specific to each antenna. SOLUTION: In the antenna system, a plurality of antennas 21 are connected to a wireless module 41 via coaxial cables 22 respectively and the wireless module 41 can select one or more antennas 21 whose communication state is excellent. An upper cabinet 2 is pivotally supported on a lower cabinet 4 via a three-dimensional joint 3, the wireless module 41 is built in the lower cabinet 4, and the upper cabinet 2 incorporates the plurality of antennas 21. The plurality of coaxial cables 22 extended from the plurality of antennas 21 are bundled together, and the bundle passes through a through-hole 34 formed in the three-dimensional joint 3 and is connected to the wireless module 41.
