Product Details


The 4.5 meter remote sensing antenna adopts proven high performance and high reliability measures, it has multiple bands to operate such as the X band, S band and Ka band. The antenna base adopts a planetary gear reduction mechanism to improve the accuracy; the servo uses AC drive instead of DC drive to improve reliability and reduce maintenance; Precision gyro extends the life of the equipment; communication between the extensions via the CAN bus reduces the number of cables and improves reliability. 

Our remote sensing antenna have a mechanical search capability and signal tracking function for the target signal airspace, it also has the ability to receive and transmit signals to X-band satellites, more over, it can receive ship platform information, alarm information and pointing information distributed by the host computer through the network.When the antenna is aimed at the target, the downstream signal is reflected and focused to the feed corrugated horn. The signal is transmitted to the X receiving channel via the feed network for signal detection.
