Description & Specification
WR-137 H-Plane Sectoral Horn Antenna
Precision C-Band Sectoral Radiator | Standard UDR Flange Layout | 5.85 GHz – 8.2 GHz
The WI-137-UDR-10H 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 shaping 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 an ultra-wide 105° E-plane spatial coverage envelope while simultaneously preserving a focused 15° 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 10 dBi combined with an exceptionally low maximum V.S.W.R threshold of 1.3 : 1. Equipped with a standardized rectangular square UDR 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 wide-area electromagnetic susceptibility sweeps, EMI/EMC testing, multi-point communication links, tactical area protection, and mission-critical Signal Defense field installations.
