Description & Specification
WR-1150 Standard Gain Horn Antenna
High-Power UHF Radiator | Standard UDR Flange Layout | 640 MHz – 980 MHz
The WI-1150-UDR-10 is an industrial-grade, large-scale microwave Standard Gain Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for high-power directional transmission and calibration routines across the 640 MHz to 980 MHz low-frequency UHF spectrum. Meticulously optimized to manage extreme thermal and electromechanical strain, this premium radiator delivers a flat nominal directive gain profile of 10 dBi paired with exceptional phase center stability. Precision manufactured from high-grade structural aluminum alloy in Taiwan to exceed stringent measurement certifications, the massive horn flare architecture establishes a highly symmetric radiation footprint, providing uniform -3dB beamwidths of 54° in both the H-plane and E-plane matrices. Equipped with a standardized large-scale UDR Style waveguide flange layout, this robust 7.2 kg instrument safely manages continuous wave power loads up to 3000 Watts (CW) while ensuring low return loss parameters. This optimized structural geometry makes it the definitive choice for high-intensity EMI/EMC compliance sweeps, anechoic antenna measurement ranges, professional communication networks, and mission-critical Signal Defense high-field infrastructure arrays.
