3.0m earth station antenna of our company has two frewuency bands to choose: C-band and Ku-band, which is made of a shaped parabolic reflector with high gain, exceptional pattern characteristcs and low VSWR. Besides, it owns the good electric performance which meets the FCC regulation 25.209, IESS (Intelsat) or ITU-RS Recommendation 580 sidelobe specification
