Description & Specification
WR-229 Standard Gain Horn Antenna
Precision C-Band Radiator | CPR 229F/G Flange Layout | 3.3 GHz – 4.9 GHz
The WI-229-UDR-10 is a laboratory-grade microwave Standard Gain Horn Antenna professionally engineered for strict adherence to the rectangular WR-229 architectural standard. Operating continuously across the 3.3 GHz to 4.9 GHz frequency spectrum, this premium horn antenna ensures exceptional illumination consistency and stable electromechanical coupling, delivering a flat nominal directive gain profile of 10 dBi combined with an ultra-low maximum V.S.W.R threshold of 1.25 : 1. High-precision CNC manufactured from structural aluminum alloy in Taiwan, the radiator architecture establishes a highly symmetric radiation footprint with matching -3dB beamwidths of 56° in both the H-plane and E-plane matrices. Equipped with a standardized rectangular CPR 229F/G flat-to-grooved cover flange layout, this 360 g component reliably supports extreme high-power continuous wave transfers up to 800 Watts (CW). This optimized structural geometry makes it the definitive choice for EMI/EMC testing, anechoic antenna measurement ranges, satellite feed subsystems, and mission-critical Signal Defense field calibration arrays.
