Description of the Related Art Since a conventional rotary base of a receiving base station has only one receiving antenna, when measuring electric field strength or adjusting the direction in a direction where the electric field strength is strong, the rotary base must be rotated at least over the entire circumference. It has to be rotated by 360 degrees, which is an angle, which takes time for measurement and adjustment. In addition, it may be difficult to rotate the turntable at high speed around the entire circumference due to the weight and strength of the turntable and the antenna attached to the turntable.
