A reflector antenna includes a reflector, a primary radiator, an arm, and a feed unit (a coaxial cable and a coaxial connector). The reflector has a reflecting surface for reflecting a radio wave, and the reflecting surface is shaped as a paraboloid of revolution. The primary radiator is arranged on a focus side of the reflector, and radiates a radio wave from the focus side toward the reflecting surface. The arm is arranged to extend from the reflecting surface side to the focus side of the reflector, and supports the primary radiator so as to be rotatable with respect to the reflector. The feed unit feeds the primary radiator via the arm so that the direction of the arm and the direction of polarization of the radio wave radiated from the primary radiator are perpendicular to each other.
