The HS-159-UDR-15A-NF is a professional-grade WR-159 Waveguide Horn Antenna expertly engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for advanced laboratory testing and high-frequency validation. Operating within the C-Band spectrum across the continuous 4.9 to 7.05 GHz band, this premium radiator provides a highly stable symmetrical 54° radiation envelope combined with a calibrated nominal gain of 15 dBi. Featuring a high-durability N-Female connector interface with a standardized WR-159 / UDR flange layout, it ensures flawless structural impedance coplanarity and ultra-low-loss power transfer, safely managing peak power loads up to 380 Watts. Precision structured from high-grade aluminum alloy with an SUS-303 stainless steel interface port in Taiwan, it exhibits exceptional mechanical longevity, a robust 501g profile, and excellent pattern isolation metrics combined with a maximum V.S.W.R threshold of 1.25 : 1. It stands as the definitive choice for radar calibration, automated antenna characterization ranges, industrial EMI/EMC compliance verification, and mission-critical Signal Management testing arrays.
