System description
Tianyi Satcom 13meter Carbon fiber earth station antenna has perfect performance for transmit/ receive and receive only applications for S through Q-band frequencies with its own technology. The whole Carbon fiber reflector design of the antenna contains high precision-formed panels, truss radials and hub assembly. The feature of the antenna is to adopt Cassegrain feed and sub-reflector design, with such results as high gain, low noise temperature, high antenna efficiency and excellent rejection of noise and microwave interference.
