7.3M Earth Station Antenna Description
7.3-meter antenna, which uses a shaped parabolic reflector, provides high gain and exceptional pattern characteristics as well as low VSWR. Its electric performance meets the FCC regulation 25.209, IESS (Intelsat), or ITU-RS Recommendation 580 sidelobe specification (domestic and international standards). The main reflector surface is comprised of 16 individual adjustable aluminum panels. The panels of the main reflector are comprised of aluminum sheets and ribs which are stretch-formed, and are riveted on the special mould. The 7.3m antenna structure consists of the pedestal, reflector, sub reflector and the feed system.
