Description & Specification
WI-090-A1-25 Standard Gain Horn
WR90 (WG16) X-Band Waveguide Horn | 8.2 GHz – 12.4 GHz | 25 dBi
The WI-090-A1-25 is a high-performance standard gain horn antenna professionally engineered for X-band frequency applications. Operating within the 8.2 GHz to 12.4 GHz spectrum, it provides an exceptional high-gain profile of 25 dBi (24-26 dBi). Utilizing the standardized WR90 / WG16 rectangular waveguide architecture and precision-machined UBR UG-39/U flange interface, it is an essential instrument for Signal Integrity verification, antenna gain calibration, and professional EMI/EMC testing environments where high directivity and accuracy are critical.
