Description & Specification
18.0 GHz to 26.5 GHz WR-42 K-Band Standard Gain Horn Antenna
Model: HS-042-UBR-10-NA | Precision Calibration Grade | 500W CW Power
The HS-042-UBR-10-NA is a high-precision K-Band Standard Gain Horn Antenna professionally engineered for the WR-42 standard. Operating across the 18.0 GHz to 26.5 GHz spectrum, this antenna delivers a consistent and precision-calibrated 10 dBi gain. Featuring a Direct Waveguide Input with a standardized UG-419/U (UBR) flange, it ensures low-loss power transfer for high-energy applications up to 500 Watts (CW). It is an essential instrument for EMI/EMC testing, satellite research, and precision antenna gain characterization.
