3.7m ring focus antenna RF specification can adhere to FCC Regulation25.209,IESS and ITU-RS.580 5,INMARSAT, ASIASAT,INTELSAT, APT and CHINASAT,etc.
3.7m ring focus antenna reflector incorporates stretch-formed doubly contoured panels with matched radials and hub for ease of field alignment. The standard designed azimuth over elevation pedestal provides a cost-effective solution for high stiffness and stability, full orbital arc coverage and fine drive performance, and ensures the pointing accuracy required for Ku-band operation.
Highlighted Features:
*Meets CCIR 580 and INTELSAT Requirements
*Meets CCIR 580 and INTELSAT Requirements
*CP/LP switchable feed
*High RF performance
*Galvanized Stainless steel hardware
*Different frequency ranges from many feed configurations
* Antenna reflector be pre-assembly in works, special designed taper-pin easy instllation and ensure on
site assembly accuracy, no theodolite required.
