Description & Specification
15.0 GHz to 22.0 GHz WR-51 K-Band Standard Gain Horn Antenna
10 dBi Gain Precision | Direct Waveguide Input | Model: WI-51-UBR-10
The WI-51-UBR-10 is a high-precision K-Band Standard Gain Waveguide Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for definitive electromagnetic measurements and high-frequency communication operations within the continuous 15.0 GHz to 22.0 GHz spectrum. Designed as an uncompromised calibration standard, this premium radiator provides a highly predictable and consistent nominal gain profile of 10 dBi combined with perfectly symmetric 54° horizontal and vertical radiation envelopes. Featuring a Direct Waveguide Input equipped with a standardized UBR Style square interface flange, it completely eliminates transition insertion losses from external coaxial adapters to achieve peak signal fidelity and low return loss metrics. Precision CNC machined from high-grade aerospace structural aluminum alloy in Taiwan, the robust housing effortlessly sustains continuous wave power loads up to 500 Watts (CW). It stands as the essential choice for automated anechoic chamber testing, satellite sub-system evaluation, precision antenna characterization ranges, and mission-critical Signal Defense infrastructure deployments requiring outstanding electrical integrity.
