Description & Specification
K-Band Standard Gain Horn
WR-42 Waveguide | 18 GHz - 26.5 GHz | Model: HS-042-UBR-15A-KF
The HS-042-UBR-15A-KF is a high-precision WR-42 Standard Gain Waveguide Horn Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for microwave RF measurement applications. Operating within the high-frequency K-Band spectrum across the continuous 18 GHz to 26.5 GHz band, this premium antenna features a standardized WR-42 waveguide interface with a UBR flange. Delivering a stable nominal gain of 15 dBi with uniform radiation characteristics, it ensures flawless structural impedance coplanarity and ultra-low-loss power transfer, safely managing wave power loads up to 200 Watts. Precision machined from high-grade structural aluminum alloy in Taiwan, it exhibits exceptional electromechanical longevity, a lightweight 45g profile, and a maximum V.S.W.R threshold of less than 1.25 : 1. It stands as the definitive choice for Signal Integrity verification, antenna gain calibration, and professional laboratory setups where high-frequency accuracy and structural reliability are paramount.
