3.7m antenna Description
3.7m earth station antenna uses a shaped parabolic reflector which can provides high gain, exceptional pattern characteristics and low VSWR. It is designed with a dual shaped shifted focal axis reflector so that the system can get higher gain and lower sidelobe, which is according to the standard of of INTELSAT IESS and CCIR Rec.580-4, INMARSAT, ASIASAT, APT and CHINASAT, etc. Its main reflector is stretch-formed aluminum panels with high accuracy, which is riveted with rings and ribs on the precise mould so that the antenna has simple,reliable structure and convenient assembly way.
