3.7m antenna Description


3.7-meter C/Ku earth station antenna, which uses a shaped parabolic reflector, provides high gain and exceptional pattern characteristics as well as low VSWR. A dual shaped shifted focal axis reflector is so designed for the antenna that the system gets higher gain and lower sidelobes, which meet the requirements of INTELSAT IESS and CCIR Rec.580-4, INMARSAT, ASIASAT, APT and CHINASAT, etc. The main reflector adopts stretch-formed aluminium panels with high accuracy riveted with rings and ribs on the precise mould, ensuring the antenna structure to be simple, reliable and convenient for installation.
