3M satellite communication antenna which is firstly developed by our company is one of a series of ring focus satellite communication antenna. This type of product adopts the most advanced forming theoretical design, which possesses the performance of high gain, low sidelobe, low cross polarization and fair matching, and fully satisfies the international standard. 

 3M satellite communication antenna reflector adopts high precision technology of advanced skin stretch rivet forming. Its structure is scientific, reasonable, stable and reliable, and also achieves requirement of complete interchange. Its appearance is novel and beautiful, which is the deal antenna to set up VAST station.
