3.7m antenna Description

Our 3.7m VSAT antenna is made of shaped parabolic and dual shaped shifted focal axis reflector which can provide high gain, exceptional pattern, low VSWR and sidelobe. It has C-band and Ku-band frequency as option. And it has high accurate stretch-formed aluminum panels which is fastened with rings and ribs on the precise mould. This kind of reflector makes antenna simple and stable, easy to assemble. Besides, the dual shaped shifted focal axis reflector is designed depending on the requirements of INTELSAT IESS and CCIR Rec.580-4, INMARSAT, ASIASAT, APT and CHINASAT, etc.
