High Gain 3.7 Meter 1KW Ku Band Satellite Transmit Dish Antenna
ZD-BUCA-KU-3.7M
This 3.7m large-aperture Ku-band satellite transmit dish antenna is engineered for long-distance satellite transmission, covering 13.75-14.5GHz transmit frequency with linear polarization and standard WR75 waveguide connector, supporting up to 1KW CW power capacity. It delivers superior transmit gain with VSWR limited to 1.30:1, ≥30dB cross-polarization isolation and ≤-14dB first sidelobe level for outstanding long-range signal convergence. Equipped with full manual adjustment bracket, it enables continuous azimuth adjustment from -90° to +90°, pitch 5°~90°, and ±90° manual polarization rotation for easy alignment. Featuring lightweight corrosion-resistant truss reflector, it is ideal for small & medium fixed ground stations and long-distance RF transmission tests.

This 3.7-meter ku banddish antenna is a large-aperture satellite antenna, a high-power long-distance signal transmission dedicated transmit antenna, operating on 13.75-14.5GHz transmit band with linear polarization and standard WR75 waveguide connector, which can steadily bear 1KW CW transmitting power. This ku bandtransmit antenna achieves transmit gain TX ≥52.0 + 20lg(f/14.25) dBi, VSWR within 1.30:1, ≥30dB cross-polarization isolation and ≤-14dB first sidelobe level, with much better wave convergence and stray suppression than small & medium aperture devices. This complete satellite antenna adopts full manual mechanical adjustment structure, with continuous azimuth from -90° to +90°, pitch 5°~90°, and ±90° manual polarization rotation for easy field calibration. The lightweight truss dish is sturdy and corrosion-resistant, suitable for small-medium fixed ground stations and long-range RF transmission tests, serving as the preferred ku banddish antennatransmit antenna for high-gain and high-power scenarios.
