Product Description
3.7 METER EARTH STATION RING FOCUS ANTENNA
General description
STARWIN 3.7m RX/TX antenna is specially designed for Receive and Send Antenna with good
TV signal performance with diameter of 3.7m, which is made of high accuracy stretch-formed aluminum panel with stable back structure, sub-reflector, pedestal/mount and feed
system. The 3.7m RX/TX antenna systems features with satisfactory performance of high gain,
low side lobe and reliable operation, easy to operate and maintenance. The 3.7m antenna can
work well with its corresponding LNB and Antenna Receiver, which used to Receive and Send
C band and Ku band satellite signal.
