3.0 meter ring-focus paraboloid antenna adopts gregorian antenna system, for the satellite communication applications in C-band (model WTX3-4/6) and Ku-band (model WTX3-12/14).
Aluminum panels with hot spray galvanized and heat-diffusing white paint are shaped main reflector, mounted on a Az. over El. pedestal. The subreflector is made of cast-aluminumand and the load-carrying component are made of carbon steel.
It is provided with a Rx/Tx (2 ports) feed with corrugated horn, operates in circular or linear polarization optionally.
Antenna is of optimized R.F. specification, it is reliable and convenient to operate and maintain.
