Description & Specification
26.5 GHz to 40.0 GHz WR-28 Ka-Band Standard Gain Horn Antenna
Model: WI-28-UBR-15 | 15 dBi Precision Gain | 500W High Power
The WI-28-UBR-15 is a high-precision Ka-Band Standard Gain Horn Antenna professionally engineered for the WR-28 waveguide standard. Operating across the expansive 26.5 GHz to 40.0 GHz spectrum, this antenna delivers a consistent and precision-calibrated 15 dBi gain. Featuring a Direct Waveguide Input with a standardized UG-599/U (UBR) flange, it ensures ultra-low-loss power transfer for high-energy applications up to 500 Watts (CW). It is an essential instrument for millimeter-wave EMI/EMC testing, satellite research, and precision antenna characterization.
