Description & Specification
26.5 GHz to 40.0 GHz WR-28 Ka-Band Standard Gain Horn Antenna
Model: HS-028-UBR-25-NA | 25 dBi High-Gain Precision | 500W CW Power
The HS-028-UBR-25-NA is a high-performance Ka-Band Standard Gain Horn Antenna professionally engineered for the WR-28 waveguide standard. Operating across the 26.5 GHz to 40.0 GHz spectrum, this antenna delivers a consistent and precision-calibrated 25 dBi gain with narrow-beam precision. 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 in professional laboratory environments.
