The invention relates to the technical field of communication base stations, in particular to a cable anti-galloping device based on a communication base station, which comprises a fixing frame, the fixing frame is hexagonal, a blade is arranged at the center position of the fixing frame through a rotating mechanism, a reflective coating is sprayed on the surface of the blade, threaded holes are formed in the six corners of the fixing frame, and the threaded holes are communicated with the fixing frame. And a threaded column is connected into the threaded hole through threads, a rotary knob is fixedly welded to the inner end of the threaded column, a ball groove is formed in the outer end of the threaded column, a ball body is installed in the ball groove, and rubber pads are glued to the contact faces of the ball groove and the ball body. According to the invention, through the arrangement of the first spring and the second spring, when the cable vibrates or gallops, a part of vibration and galloping energy is consumed through work, and the first spring and the second spring absorb and relieve the energy through elastic deformation, so that the cable can be subjected to damping and anti-galloping protection.
