Description & Specification
15.0 GHz to 22.0 GHz WR-51 Standard Gain Horn Antenna
Model: WI-51-UBR-20 | 20 dBi Gain | 500W CW Power
The WI-51-UBR-20 is a high-performance Standard Gain Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for strict compliance with the WR-51 standard. Operating within the 15.0 GHz to 22.0 GHz spectrum, this antenna delivers a consistent and precision-calibrated 20 dBi gain. Featuring a Direct Waveguide Input with a standardized UBR 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.
