Description & Specification
HS-51-UBR-25-KF Standard Gain Horn Antenna
High-Power Microwave Solution | Precision WR-51 Waveguide | 15 GHz – 22 GHz | 25 dBi
The HS-51-UBR-25-KF is a high-performance Standard Gain Horn Antenna specifically engineered for professional wideband microwave testing across the 15 GHz to 22 GHz frequency spectrum. This laboratory-grade radiator provides a nominal gain of 25 dBi with exceptionally linear radiation patterns, making it an essential instrument for high-frequency signal analysis, anechoic chamber calibrations, and EMC pre-compliance testing. Featuring a high-precision WR-51 Waveguide structure with a standard UBR Flange, it supports maximum power handling up to 180W (CW) with a low VSWR of 1.3. Expertly manufactured from premium aluminum in Taiwan, it is built to meet demanding industrial and scientific calibration standards.
