EGOSAT 1.2m Ku/Ka/X band flyaway antenna system are designed to provide high speed stow and deploy through its simple and robust structure and light weight material.
The reflector is composed of six panels, use fast-lock speed connection thus avoiding the need of installation tools. Az/El adjustment can be locked, El adjustment is by fast-tune and fine-tuning combined in one device to facilitate the operation. The support can be deployed flexibly, the whole structure of the antenna is designed to be easy to disassemble and assemble with features including all antenna parts/components packed in 1 box, small size, light weight and high stability.
The antenna has been designed to be airline checkable and can be field .
