Abstract
The utility model provides an adjusting device for a base station antenna electric declination angle. The adjusting device for the base station antenna electric declination angle comprises an adjusting circuit which determines the relation between a base station antenna electric declination angle value and an output voltage of an analog-digital converter. The adjusting circuit comprises a linear variable potentiometer whose first fixed terminal is connected with a power supply of the analog-digital converter and whose second fixed terminal is connected to the ground. The adjusting device for the base station antenna electric declination angle further comprises a transmission mechanism and a processor. The transmission mechanism is respectively connected with a phase shifter and a movable terminal of the linear variable potentiometer. The processor is connected with the transmission mechanism, receives a preset angle value, calculates the output voltage corresponding to the preset angle value, controls the transmission mechanism so that the movable terminal of the linear variable potentiometer and the phase shifter can be driven to move, and therefore adjusts the electric declination angle of the base station antenna.
