^´ The first dual reflector ring focus antenna model was successfully developed in the 1980's. It fundamentally resolved problems of achieving high performance design on medium and small aperture antennas for satellite communication earth stations. We are the first to manufacture and introduce the high performance spectrum multiplexing antenna feed with 500MHz receiving and 575MHz transmitting band width respectively. We are also the first to master the multimode horn, corrugated horn feed, high efficiency low side lobe antenna technology, transforming it from theoretical understanding to commercial practices. All of these cumulative knowledge propelled satellite communication antenna technology forward. In recent years, we have kept in step with new developments of international antenna technologies and have developed C/Ku, S/X, dual-band common feed technology, multiple beam satellite communication antenna technology, airborne satellite communication antenna technology, super-broad band spectrum multiplexing feed technology with receiving and transmitting 800MHz band width respectively, broad band multimode null tracking antenna technology.

On antenna and control/servo tracking technology, the structural optimization designs of antenna truss mount, wheel-track mount, turntable mount and drive control and tracking technology have secured us the leading position. Gyro-stabilized high precision mobile tracking antenna technology for shipborne satellite communication station and the airborne control and tracking technology for satellite communication have further established us as a leading technology provider.

Fine electrical performance of our products allows the antennas to feature broad band operation, high efficiency, low side lobe envelope, high polarization discrimination ability, low noise temperature and small VSWR. The mechanical performance of the antennas is also well defined; steady steel structure,reasonable controllability,the antennas are reliable and durable. Functions of the antenna and servo systems are complete and integrated,easy to operate and control,the tracking accuracy is high and reliable.

6.2m,7.3m and 15m C band antennas were the first satellite communication earth station antennas to have approvals to access the INTELSAT network and installed in the market.After,the 2.4m,3m,3.7m,4.5m ku band series antennas have been manufactured and become the first series of antenna products approved to access the Asian satellite communication network as a groups.

In the telemetry & telecontrol antenna field, the 1-12.4GHz all band operating aperture antenna technology, millimeter wave high speed high precision telemetry & telecontrol antenna technology, ultra-short wave multipoint frequency multifunction and common servo telemetry & telecontrol antenna array technology, and overhead tracking technology for three-axis mount have been well developed.
