Antesky is a professional vsat antenna manufacturer, which was established in 1985 under the support of Chinese governmental
research institutions. At previous time, we mainly customized antennas for Chinese aerospace and military application. From the year 2008, we began to produce civilian antennas. However, Antesky manufactures civilian antennas according to military standard all the time, so the antenna quality is with high reputation in the world. Antesky can provide antennas from 3m diameter to 50m diameter, including vsat antenna, Large Satellite Dish, TVRO Antenna, Flyaway Antenna and Marine TV Antenna etc.
