Model: ATSK-300CST or ATSK-300KST
3.0M satellite communication antenna which is firstly developed by our company isone 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 side lobe, low cross polarization, and fully satisfies the international standard.
The reflector of 3.0m satellite communication antenna adopts advanced surface stretching and rivet forming technology, which structure is reasonable, stable and reliable, and it also meets the requirements of complete interchange. Antesky is a professional VSAT antenna supplier.
