High G/T, Excellent Pattern
Hot-spray zinc Steel Ground
Offset Parabolic
Mount Assembly
2-port Linear Polarization
1.8Meter antenna consists of two varieties, offset /ring focus antenna, providing Tx/Rx 2-port feed in linear polarization, can offer superior Tx/Rx performance.
1.8 M antenna RF specification can adhere to FCC Regulation25.209, IESS and ITU-RS.580-5, INMARSAT, ASIASAT, INTELSAT, APT and CHINASAT, etc.
1.8M 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.
