The WI-112-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 7.05 GHz to 10.0 GHz X-Band spectrum. Meticulously optimized to enforce highly consistent 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 flare geometry establishes a highly uniform radiation footprint, providing matching -3dB beamwidths of 52° in the H-plane and 50° in the E-plane matrix. Equipped with a standardized rectangular square UBR Style cover flange layout, this ultra-lightweight 85 g component ensures flawless electromechanical coupling and safely manages continuous wave power loads up to 500 Watts (CW). This optimized structural architecture avoids destructive field distortion modes, rendering it the definitive choice for EMI/EMC testing, anechoic antenna measurement ranges, and mission-critical Signal Defense field calibration networks.
