1.8 meter Ku-band Satellite Communication Antenna

This 1.8m Ku-band manual transmit-receive integrated satellite antenna supports both Ku receiving and transmitting bands, with receiving range 10.7–12.75GHz and transmitting range 13.75–14.5GHz. It can withstand 1kW CW transmit power and achieves Tx-Rx isolation over 85dB.

Designed with linear polarization, it features VSWR ≤1.25:1, cross-polarization isolation ≥35dB and first sidelobe level ≤-14dB, whose sidelobe envelope complies with CCIR.580 standard. Equipped with standard WR-75 waveguide port, the feed insertion loss is controlled below 0.5dB.It adopts a single-column manual mount with continuously adjustable azimuth (±90°), elevation (0°–90°) and polarization (±90°) with locking structure. The antenna owns outstanding wind resistance: normal operation at 80km/h and no structural damage under 200km/h wind when locked at zenith. Adaptable to outdoor environment of -40℃~60℃ and 0%~100% humidity, it is widely used in fixed-station two-way VSAT satellite communication systems.
