1000W 3.7m Ku-Band Satellite Transmit Antenna

This 3.7m Ku-band manual parabolic transmit antenna features linear polarization and withstands 1kW CW power. It delivers high transmit gain with first sidelobe ≤-14dB and cross-polar isolation ≥30dB. The manual mount supports continuous adjustable azimuth, elevation and polarization with locking function, ideal for large-scale VSAT satellite uplink communication.

Product Detail

This 3.7m Ku-band parabolic transmit antenna operates within 13.75–14.5GHz transmit frequency range with linear polarization and supports 1kW continuous wave power, equipped with standard WR75 waveguide connector. It achieves transmit gain over 52dBi, VSWR ≤1.3:1, first sidelobe ≤-14dB and cross-polarization isolation ≥30dB with outstanding RF performance. Adopting split skeleton reflector and manual mount, it allows continuous adjustable azimuth (-90°~+90°), elevation (5°~90°) and polarization (±90°) with locking mechanism. Anti-corrosion metal structure makes it widely applied in large fixed VSAT satellite uplink stations.
