Description & Specification
WR-137 H-Plane Sectoral Horn Antenna
Precision C-Band Sectoral Radiator | Standard UAR Flange Layout | 5.85 GHz – 8.2 GHz
The WI-137-UAR-12H is a laboratory-grade microwave H-Plane Sectoral Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for specialized radiation pattern control and calibration routines across the 5.85 GHz to 8.2 GHz C-Band spectrum. By flaring specifically within the horizontal H-plane geometries, this premium sectoral horn enforces an asymmetric illumination path, delivering a broad 86° E-plane spatial coverage envelope while simultaneously preserving a focused 28° H-plane beamwidth aperture. Precision CNC machined from high-grade structural aerospace aluminum alloy in Taiwan, the radiator maintains a flat nominal directive gain profile of 12 dBi combined with an exceptionally low maximum V.S.W.R threshold of 1.3 : 1. Equipped with a standardized rectangular square UAR Style cover flange layout, this robust 580 g component ensures flawless electromechanical coupling and safely manages continuous wave power loads up to 800 Watts (CW). This optimized structural architecture avoids destructive field distortion modes, rendering it the definitive choice for broad-area monitoring, EMI/EMC testing, high-capacity communication links, tactical area protection, and mission-critical Signal Defense field installations.
