Abstract
An automatic feedback adjustment device for a digital antenna includes a digital antenna unit, a trafficator, a tuner, a demodulator, an antenna direction driver unit, a secondary controller, and a primary controller. The digital antenna unit is a digital video/broadcasting antenna system. The trafficator is connected to the digital antenna unit to retrieve direction data associated with the actual elevation angle and direction. The tuner is connected to the digital antenna unit and the demodulator is connected to the tuner in order to receive and convert a transmission signal from a transmission terminal into the video data and a received-signal quality signal. The antenna direction driver unit is connected to the digital antenna unit in order to drive adjustment of direction and elevation angle of the antenna. The secondary controller is connected to the trafficator, the demodulator and the antenna direction driver unit to receive the data of the actual antenna direction, the video data, and the received-signal quality signal and supplies an antenna drive signal. The primary controller is connected to the Internet, the storage device and secondary controller to retrieve and store the optimum direction and elevation angle for the antenna to receive signals and analyze and calculate data of the optimum signal receiving direction for the secondary controller and the secondary controller drives the antenna direction drive unit to control the digital antenna unit to automatically adjust to the optimum receiving direction.
