Description & Specification
8.2 GHz to 12.4 GHz WR-90 Sectoral Horn Antenna
Model: WI-90-UBR-20 | 20 dBi Gain | 500W CW Power
The WI-90-UBR-20 is a high-performance Sectoral Waveguide Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for strict compliance with the WR-90 standard. Operating within the 8.2 GHz to 12.4 GHz X-Band spectrum, this antenna delivers a consistent and precision-calibrated 20 dBi gain. Featuring a Direct Waveguide Input with a standardized UBR UG-39/U flange, it ensures low-loss power transfer for high-energy applications up to 500 Watts (CW). Manufactured from high-grade structural aluminum alloy via precision CNC machining in Taiwan, it exhibits exceptional electromechanical longevity and excellent pattern stability. It stands as an essential instrument for EMI/EMC testing, antenna gain characterization, and precision radar calibration setups demanding uncompromised performance parameters.
