The WR284 Standard Gain Horn Antenna is a laboratory-grade microwave radiator meticulously engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for directional transmission, antenna calibration, and advanced diagnostics across the continuous 2.6 GHz to 3.95 GHz S-Band spectrum. Optimized to preserve absolute electromechanical stability, this premium antenna delivers a flat nominal directive gain profile of 15 dBi combined with exceptional Signal Integrity and low return reflection loss. Precision CNC machined to standard WR284 dimensions in Taiwan, the advanced launch architecture supports dual-polarization deployments, maintaining uniform -3dB beamwidths of 25° in the horizontal plane and 24° in the vertical plane matrix. Equipped with a standardized precision Type01 Flange Interface layout, this robust 2.2 kg industrial-grade asset ensures flawless, secure integration with standard microwave sub-systems and distribution networks. Its optimized mechanical structure completely blocks path distortion modes, rendering it the definitive choice for radar systems, international EMI/EMC anechoic chamber testing, spectrum management routing, and mission-critical Signal Security laboratory verification setups.
