Description & Specification
WR-137 E-Plane Sectoral Horn Antenna
Precision C-Band Sectoral Radiator | Standard UDR Flange Layout | 5.85 GHz – 8.2 GHz
The WI-137-UDR-15E is a laboratory-grade microwave E-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 vertical E-plane geometries, this premium sectoral instrument enforces an asymmetrical illumination path, delivering a broad 75° H-plane spatial coverage envelope while simultaneously preserving a tightly focused 15° E-plane beamwidth aperture. Precision CNC machined from high-grade structural aluminum alloy in Taiwan, the radiator maintains a calibrated directive gain profile of 15 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 520 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 tactical links, radar simulation networks, and mission-critical Signal Defense field installations.

Controlled Sectoral Pattern
The targeted E-plane flare mechanics form an extensive 75° asymmetric coverage swath in the H-plane, allowing for expansive vertical or horizontal sector coverage based on mounting orientation.
800W High-Power Domination
Robustly engineered structural core effortlessly manages up to 800 Watts of continuous wave power loads without experiencing thermal variation or boundary distortion under high-intensity transmitter matching.
Taiwanese Engineering Excellence
Precision designed and manufactured in Taiwan under strict industrial quality control parameters, delivering exceptional dimensional alignment tolerances, precise flare configurations, and traceable reference criteria.
C-Band Signal Security
Optimized continuously across the full 5.85–8.2 GHz spectrum, effectively neutralizing internal signal degradation paths and return reflections to preserve pure signal tracing parameters inside mission-critical networks.
Lightweight Aluminum Build
Weighing only 520 g, its sleek aluminum enclosure provides high structural rigidity while remaining easy to deploy on tactical masts or portable tripod systems during demanding field operations.
