The WI-340-UDR-15 is a high-performance WR-340 Waveguide Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for precision electromagnetic measurements and high-power operational environments within the 2.2 GHz to 3.3 GHz spectrum. Strategic coverage includes critical frequencies for S-Band radar systems and specialized industrial microwave applications, delivering a highly consistent and focused 15 dBi nominal gain profile. Meticulously designed to handle maximum continuous wave power loads up to 1000 Watts (CW), it ensures unwavering signal integrity and mechanical stability combined with a maximum V.S.W.R threshold of 1.25 : 1. Precision CNC machined from high-grade aerospace structural aluminum alloy in Taiwan, the calculated launch geometry yields highly stable and reproducible 30° horizontal and 29° vertical beamwidth profiles with sharp boresight resolution. It stands as the definitive choice for automated antenna calibration ranges, industrial microwave heating installations, intensive EMI/EMC immunity testing, and mission-critical Signal Defense infrastructure configurations demanding uncompromised electrical parameters.
