The HR-1050G-VF is a laboratory-grade, broadband Open Boundary Quad-Ridged Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for high-fidelity directional radiation tracking, antenna gain calibration, and advanced millimeter-wave diagnostics across the continuous 10 GHz to 50 GHz frequency spectrum. Meticulously optimized to expand standard bandwidth constraints, this premium antenna features a precision-machined 1.85mm Female (V) coaxial launcher interface, ensuring seamless structural impedance coplanarity and minimal insertion loss across critical high-frequency sectors. The unique open boundary geometric architecture is intentionally profile-shaped to eliminate severe sidewall energy trapped reflections and minimize aperture fringe scattering, establishing exceptionally clean, symmetrical, and repeatable radiation pattern profiles. Precision CNC machined from high-grade structural alloys in Taiwan, this component guarantees outstanding electromechanical longevity and maximum co-polarization isolation metrics under continuous usage. It stands as the definitive choice for next-generation 5G millimeter-wave evaluation grids, high-bandwidth satellite communication development, industrial EMC/EMI compliance scanning, and mission-critical anechoic testing environments demanding uncompromised performance parameters.
