The HS-159-UAR-10H-NF is a high-performance WR-159 H-Plane Sectoral Horn Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for mission-critical RF operations and tactical scanning layouts. Operating within the C-Band spectrum across the continuous 4.9 GHz to 7.05 GHz frequency range, this premium antenna features a specialized flare in the H-plane to provide an ultra-wide 105° horizontal sectoral beamwidth profile, making it highly optimized for localized Signal Security area surveillance. Integrating a direct waveguide input layout with a standardized CPR 159F / CPR 159G flange mating face and a high-durability stainless steel N-Female interface connector, it ensures flawless structural impedance coplanarity, minimal return loss, and ultra-low-loss power transfer. Precision structured from high-grade aluminum metal alloy in Taiwan, it exhibits exceptional mechanical longevity, a lightweight 800g profile, and highly stable radiation parameters paired with a maximum V.S.W.R threshold of 1.25 : 1, safely managing continuous wave power loads up to 600 Watts (CW). It serves as the definitive choice for direction finding, automated antenna calibration ranges, industrial EMI/EMC emissions monitoring, and professional Signal Defense infrastructure integration setups.
