Global Skyware 1.2m Rx/Tx Extended Ku-Band Class II Antenna System, Type 123
– The Skyware Global 1.2m Rx/Tx Extended Ku-Band Class II Antenna is a rugged commercial-grade satellite antenna system.
– It features a thermoset-molded reflector with a network of support ribs that strengthens the antenna.
– The antenna has long focal length optics for low cross-pol performance and fine azimuth and elevation adjustments.
- The antenna model is 62-1236201 and the Intelsat Standard is Standard G (IESS 601).
- The RF performance specifications include effective aperture, operating frequency, polarization, gain, 3 dB beamwidth, sidelobe envelope, antenna cross-polarization, contour, VSWR, and isolation.
- The feed interface for TX is WR75 Flat Flange and for RX it is also WR75 Flat Flange.
- The mechanical performance specifications include reflector material, antenna optics, mount type, elevation and azimuth adjustment ranges, and mast pipe interface.
- The environmental performance specifications include wind loading for operational, functional survival, and ultimate survival, operational and survival temperature, humidity, atmosphere, solar radiation, and shock and vibration.
