The WI-430-UDR-10H is a high-precision WR-430 H-Plane Sectoral Horn Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for specialized wide-vertical illumination fields. Operating within the low-frequency L/S-band spectrum across the continuous 1.72 GHz to 2.60 GHz frequency band, this premium antenna is expertly flared in the H-plane to deliver a distinct, highly predictable Fan-Beam radiation pattern profile (16° H-plane x 112° E-plane) combined with a calibrated nominal gain of 10 dBi. Featuring a Direct Waveguide Input interface with a standardized UDR Style universal flange mating face, it ensures flawless structural impedance coplanarity and ultra-low-loss power transfer, safely managing continuous wave power loads up to 1000 Watts (CW). Precision CNC machined from high-grade structural alloy in Taiwan, it exhibits exceptional electromechanical integrity, a lightweight 1.6 kg profile, and excellent pattern isolation metrics. It stands as the definitive choice for wide-vertical area monitoring grids, automated antenna characterization ranges, industrial EMI/EMC compliance validation scanning, wireless network research, and mission-critical Signal Defense verification setups demanding uncompromised performance parameters.
