Alignsat 3.7M Earth Station Antenna
- Alignsat 3.7m Earth Station AntennaDownload
Description
Alignsat 3.7m antenna delivers exceptional high performance for transmit/ receive application in C, Ku, ka, X band in Tx/ Rx 2 port or Rx 2 port with high gain, low noise and low microwave interference.
Alignsat 3.7m antenna offers a fine reflector design with a stretch formed double contoured panels, strong back struts and hub for ease of field alignment. The standard designed azimuth over elevation pedestal provides a cost-effective solution for ground or roof installation with high stiffness and stability, full orbital arc coverage and fine drive performance, and ensures the pointing and tracking accuracy.
The electrical performance is compliant with FCC and ITU-RS-580 sidelobe specifications and Intelsat, Eutelsat, INMARSAT, ASIASAT, APT and CHINASAT, etc requirement.
Performance Strength
- High quality aluminum reflector panels and galvanized steel backup structure.
- C, Ku, Ka, X band Available, meeting FCC and ITU-RS-580 requirements.
- Galvanized steel elevation over azimuth pedestal.
- Fixed foundation and Non penetrating foundation optional for wider choice.
