Description & Specification
5.85 GHz to 8.2 GHz WR-137 High-Power Horn Antenna
Modular Multi-Segment Build | High Gain Directivity | Model: WI-137-UDR-25
The WI-137-UDR-25 is an industrial-grade, large-scale microwave Standard Gain Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for ultra-high performance directional transmission and precision calibration routines across the 5.85 GHz to 8.2 GHz C-Band spectrum. Optimized to deliver a commanding and highly calibrated directive gain profile of 25 dBi, this high-fidelity instrument achieves an exceptionally narrow and focused directional radiation footprint with a -3dB beamwidth of only 10° horizontal and 11° vertical. High-precision manufactured from structural aluminum alloy in Taiwan, the antenna features an advanced, divisible Modular Multi-Segment Structure that addresses transportation challenges for large C-band apertures while guaranteeing flawless mechanical stability and a maximum V.S.W.R threshold of 1.3 : 1. Equipped with a standardized rectangular square UDR Style Flange interface, this heavy-duty 11 kg radiator efficiently manages massive continuous power loads up to 800 Watts (CW) with zero electromechanical boundary degradation. It stands as the definitive choice for intense high-field EMI/EMC compliance testing, long-range transmitter calibration, professional wireless chambers, and mission-critical Signal Defense infrastructure arrays.
