Description & Specification
HS-042-UBR-25-KF Standard Gain Horn Antenna
18 to 26.5GHz | High Gain 25 dBi | WR42 Waveguide
The HS-042-UBR-25-KF is a precision WR42 Standard Gain Horn Antenna engineered for high-frequency millimeter-wave applications. Operating within the 18 to 26.5 GHz range, it delivers a sharp, directional beam with 25 dBi gain. This antenna is an essential calibration device for measuring the gain of other antennas and is widely used in EMI/EMC testing, direction finding, and surveillance. Crafted from high-grade aluminum with a K-Female connector and UBR flange, it ensures ultra-low signal reflection (V.S.W.R 1.25) and consistent laboratory performance.
