3.7m VSAT dish 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.
3.7m VSAT dish Features
You can choose linear or circular polarized feed system according to your requirement
Aluminum reflector formed with stretch way, using self-aligning
Antenna performs well in electric specificaiton
Fixed or motorizable pedestals
