The HS-062-UBR-25A-SF is a high-performance Ku-Band Standard Gain Waveguide Horn Antenna professionally integrated with a precision waveguide-to-coaxial adapter, engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF). Operating within the microwave spectrum across the continuous 12.4 GHz to 18.0 GHz band, this system delivers an exceptionally high directional gain of 25 dBi. Featuring a precise WR-62 interface layout with a standardized UG-419/U (UBR Style) flange face and a robust coaxial SMA-Female connector interface, it ensures flawless structural impedance coplanarity and ultra-low-loss power transfer. Safely managing continuous wave power loads up to 250 Watts (CW), this radiator is precision machined from high-grade structural aluminum alloy in Taiwan, yielding excellent pattern stability paired with a maximum V.S.W.R threshold of 1.25 : 1. It serves as an essential instrument for EMI/EMC Testing, satellite communication research ranges, and high-fidelity antenna gain measurement configurations where superior Signal Integrity is paramount.
