Description & Specification
8.2 GHz to 12.4 GHz WR-90 X-Band Standard Gain Horn Antenna
Model: HS-090-UBR-20-NA | 20 dBi Gain | X-Band Precision
The HS-090-UBR-20-NA is a high-performance Standard Gain Horn Antenna professionally engineered for the WR-90 waveguide standard. Operating within the 8.2 GHz to 12.4 GHz spectrum, this antenna delivers a precision-controlled radiation pattern with a consistent 20 dBi gain. Featuring a Direct Waveguide Input and standardized UG-39/U (UBR) flange, it is a critical instrument for EMI/EMC testing, radar calibration, and mission-critical Signal Defense operations where high directivity and signal integrity are paramount.
