4.5 METER EARTH STATION ANTENNA

General description

4.5m RX/TX antenna is specially designed for Receive and Send Antenna with good TV signal performance with diameter of 4.5m, which is made of high accuracy stretch-formed aluminum panel with stable back structure, sub-reflector, pedestal/mount and feed system. The 4.5m RX/TX antenna systems features with satisfactory performance of high gain, low side lobe and reliable operation, easy to operate and maintenance. The 4.5m antenna can work well with its corresponding LNB and Antenna Receiver, which used to Receive and Send C band and Ku band satellite signal.
