Description & Specification
WR187 Waveguide Horn Antenna
3.95 - 5.85 GHz | 10 dBi Gain | 1KW Power Handling | UDR Flange | Model: WI-187-UDR-10H
The WI-187-UDR-10H is a high-performance C-band waveguide horn antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF). Operating across the frequency range of 3.95 GHz to 5.85 GHz, this horn antenna delivers a nominal 10 dBi gain and accommodates high power handling up to 1KW (CW). Featuring a standard UDR waveguide flange with a low VSWR of 1.25, it provides tailored radiation directivity with a 12° H-plane and 110° E-plane (-3dB) beamwidth. Precision-machined for outstanding RF efficiency and structural reliability, it is ideally suited for high-power wireless communications, radar systems, and EMC/EMI testing setups requiring Taiwanese engineering precision.
