6.2m antenna with A—E type turning head pedestal type can realize C/Ku-band receiving and transmitting function. It satisfy GB/T19001－2008、GJB9001B-2009 Standard, and it can meet the technical regulation and requirement of ITU-T、ITU-R.
This antenna is a type of dual Dual shaped reflector antenna with high efficiency, low sidelobe and better cross-polarization isolation.
This antenna has the features of reasonable structure design, beautiful shape and high strength, as well as convenient installation and good wind resistance ability.
The antenna panel adopts 2mm thickness 2A12-O aluminum alloy plate, quenching stretch process forming, high surface precision.
The panel is coated with three proofs of strontium yellow primer and polyurethane finish. The steel structure is treated with hot dipping zinc and then coated with strontium chromate primer and polyurethane paint, all these make the antenna can adapt all kinds of bad environment.rethane paint, all these make the antenna can adapt all kinds of bad environment.
