Claims

[Scope of utility model registration request]

a rotatably pivoted antenna body with directivity;
a drive mechanism that rotates the antenna body; a sensor that detects that the antenna body has rotated by a certain angle and generates a detection signal; and a sensor that operates the drive mechanism until a detection signal is supplied from the sensor. control signal generating means that generates a drive control signal multiple times and supplies it to the drive mechanism, and an intermediate frequency signal of a tuner that receives a high frequency signal entering the antenna body and receives a desired channel. a reception state detection circuit that detects the reception state of the channel that changes according to the rotation and extracts a tuning instruction voltage according to the reception state; The number of times the antenna body is rotated to the rotational position of the antenna body corresponding to the optimum tuning instruction voltage by comparing the respective tuning instruction voltages corresponding to the moving position and selecting the optimum tuning instruction voltage that indicates the optimum reception condition. An antenna device comprising a selection means for causing the control signal generation means to generate a drive control signal.
