AST 0.9m Ku band flyaway antenna system are designed to provide high speed stow and deploy through its simple and robust structure and light weight material.
The main supporting structure of the antenna is made of carbon fiber material. The whole antenna system is 90% carbon fiber. The material is more stable, lighter weight, higher strength and more convenient for portable use.
The antenna has the characteristics of high gain, low sidelobe, superior electrical performance and communication capability of not less than 40W.
