Description & Specification
3.95GHz to 5.85GHz Standard Gain Waveguide Horn Antenna
Broadband Precision | 20 dBi Nominal Gain | Model: WI-187-UDR-20
The WI-187-UDR-20 is a high-precision Standard Gain Waveguide Horn Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) in Taiwan. Operating across the continuous 3.95GHz to 5.85GHz frequency band, it delivers a nominal directional gain of 20 dBi with low VSWR of 1.25:1. Featuring a standard WR-187 waveguide interface with UDR Flange and fabricated from premium quality aluminum, this antenna handles high RF power levels up to 1KW. It serves as an indispensable reference standard for microwave antenna pattern measurements, chamber calibration, radar surveillance, and EMC/EMI laboratory compliance testing.
