Description & Specification
WR-90 X-Band Sectoral Horn Antenna
Model: HS-090-UBR-15-NA | 8.2 - 12.4 GHz | 15 dBi | 500W
The HS-090-UBR-15-NA is a precision-engineered X-Band Sectoral Horn Antenna designed for the WR-90 waveguide standard. Operating across the 8.2 GHz to 12.4 GHz frequency range, this ultra-lightweight antenna delivers a highly specialized radiation pattern with a consistent 15 dBi gain. Featuring a direct waveguide input and a standardized UG-39/U (UBR) Flange, it is optimized to handle up to 500W of power. Manufactured from high-grade aluminum, it is the ideal instrument for EMI/EMC Testing, wide-angle field illumination, and precision antenna gain measurement systems where weight and pattern accuracy are critical.
