Description & Specification
18.0 GHz to 26.5 GHz WR-42 K-Band Standard Gain Horn Antenna
25 dBi High-Gain Precision | Waterproof Structure | Model: WI-42-UBR-25
The WI-42-UBR-25 is a high-precision K-Band Standard Gain Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for critical laboratory measurements and rugged outdoor far-field antenna arrays operating within the 18.0 GHz to 26.5 GHz spectrum. This premium model features a direct WR42 rectangular waveguide input with a standardized UG-419/U (UBR Style) flange interface layout, ensuring optimal structural impedance alignment and completely eliminating the transition insertion losses typically associated with external coaxial adapters. Providing an intensified, highly stable 25 dBi nominal gain profile coupled with precision beam envelopes (20° H-plane / 19° E-plane), it functions as an exceptional reference standard for advanced EMI/EMC compliance testing, far-field antenna gain tracking matrices, and localized directional K-band scanning. Meticulously machined from aerospace-grade aluminum alloy in Taiwan, the housing features an advanced waterproof structure to ensure electrical performance stability across severe environmental shifts, while offering full electromechanical flexibility for automated PTZ positioners, tripod matrices, and mobile scanning arrays demanding uncompromised millimeter-wave parameters.
