ABSTRACT:
A method for automatically adjusting an antenna and the system thereof are provided. The method includes driving the motor to rotate the antenna at first, so as to receive multiple first digital signals and record the position corresponding to the multiple first digital signals; comparing the multiple first digital signals to obtain the strongest first digital signal among them; driving the motor to rotate the antenna to the position corresponding to the strongest first digital signal; driving the motor to adjust the pitching angle of the antenna to receive multiple second digital signals and record the pitching angle corresponding to the multiple second digital signals; comparing the multiple second digital signals to obtain the strongest second digital signal among them; and driving the motor to rotate the antenna to the pitching angle corresponding to the strongest second digital signal.
