Abstract

The multi-frequency antenna transmission, including a drive gear, a gear train with parallel gear shafts, screw assemblies and a shifter. The transmission gears are connected to the stoppers of the screw assemblies one by one, the drive gear drives the various transmission gears to rotate, and all the stoppers rotate. The shifter pushes the stopper of one of the screw assemblies, such that the first elastic member disposed between the connection member and the stopper is compressed, and the connection member is connected to corresponding lead screw, thus the power of the stopper is transmitted to corresponding lead screw through the compressed first elastic member and the connection member, and drives the lead screw to rotate.
