Aiming at the difficult problem that the existing ballistic telemetry antenna turntable system is required to configure telemetry antennas with different received powers according to the target types， the lightweight medium-sized ballistic telemetry antenna which is easy to maintain is proposed. Elevation-azimuth type is selected for the turntable system. A mechanism for pitch axis is designed to disassemble the drive shaft from the transmission lugs without disassembling the antenna array， which adopts the shaft-locking to ensure the transmission accuracy and improve the disassembly and maintenance efficiency of the transmission system. In addition， an azimuth transmission mechanism with an adjustable center is designed for the azimuth axis. This mechanism not only improves the antenna pointing accuracy by reducing the gear gap but also realizes in-site adjustment， which greatly reduces the disassembly and maintenance difficulty at site. The telemetry antenna with pitch axis accuracy of 0.4° and azimuth axis accuracy of 0.03° meets the preset accuracy requirement and has been delivered for use， which shows excellent antenna telemetry tracking performance and provides a reference for the structure design of the other ballistic telemetry antenna.
