Description & Specification
WR-90 End Launch Standard Gain Horn Antenna
Model: HS-090-UBR-20A-E-SF | 8.2 - 12.4 GHz | 20 dBi | 300W
The HS-090-UBR-20A-E-SF is a high-performance End Launch Horn Antenna professionally engineered for the WR-90 standard. Operating within the 8.2 GHz to 12.4 GHz X-Band spectrum, this antenna features a specialized inline coaxial-to-waveguide transition, making it ideal for linear system integration where right-angle space is limited. With a consistent 20 dBi gain and exceptional VSWR (1.25), it is an essential radiator for EMI/EMC Testing, antenna calibration, and advanced Signal Integrity measurements in mission-critical environments.
