The WI-102-UBR-10 is a laboratory-grade microwave Standard Gain Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for high-fidelity directional transmission and calibration routines across the 7.0 GHz to 11.0 GHz X-Band spectrum. Meticulously optimized to enforce wide-pattern illumination paths, this premium horn antenna delivers a flat nominal directive gain profile of 10 dBi combined with an exceptionally low maximum V.S.W.R threshold of 1.3 : 1. Precision CNC machined from high-grade structural aluminum alloy in Taiwan, the advanced horn architecture establishes a highly uniform and symmetric radiation footprint, providing broad matching -3dB beamwidths of 54° in both the H-plane and E-plane matrices. Equipped with a standardized rectangular square UBR Style cover flange layout, this ultra-lightweight 82 g component ensures flawless electromechanical coupling and safely manages continuous wave power loads up to 500 Watts (CW). This optimized structural geometry avoids destructive field distortion modes, rendering it the definitive choice for broad-area field susceptibility testing, EMI/EMC diagnostics, anechoic antenna measurement ranges, and mission-critical Signal Defense field infrastructure arrays.
