Description & Specification
WR-229 Standard Gain Waveguide Horn Antenna
Precision S/C-Band Radiator | CPR 229F/G Flange Interface | 3.3 GHz – 4.9 GHz
The WI-229-UDR-20 is a laboratory-grade microwave Standard Gain Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for high-fidelity directional transmission, anechoic calibration routines, and professional laboratory range testing across the continuous 3.3 GHz to 4.9 GHz S/C-Band spectrum. Meticulously optimized to handle high continuous thermal loads and preserve electromechanical phase center stability, this premium horn antenna delivers a flat nominal directive gain profile of 20 dBi combined with an exceptionally low maximum V.S.W.R profile of 1.25 : 1. Precision CNC machined from aerospace-grade aluminum alloy in Taiwan, the advanced rectangular launch architecture establishes a highly stable radiation footprint, providing uniform -3dB beamwidths of 18° in the H-plane and 15° in the E-plane matrix. Equipped with a standardized precision CPR 229F/G (UDR Style) Flange interface layout, this robust 2100 g instrument ensures flawless leak-free electromechanical coupling, eliminates boundary signal leakage, and safely manages continuous wave power loads up to 800 Watts (CW) with zero boundary degradation. Its optimized microscopic structural tolerances avoid destructive field distortion modes, rendering it the definitive choice for high-intensity EMI/EMC compliance sweeps, automated spectrum surveillance matrices, tactical signal management, and mission-critical Signal Defense laboratory verification setups requiring uncompromised Signal Integrity paths.
