Description & Specification
5.85 GHz to 8.2 GHz WR-137 H-Plane Sectoral Horn Antenna
Model: WI-137-UAR-12H | 12 dBi Gain | 800W High Power capacity
The WI-137-UAR-12H is a high-performance Waveguide Horn Antenna professionally engineered for applications requiring specialized radiation pattern control across the 5.85 GHz to 8.2 GHz range. By flaring specifically in the H-plane to provide a broad 86° sectoral beamwidth in the E-plane, it is optimized for tactical area protection and broad-area Signal Security. Precision-machined from high-grade aluminum with a standard UAR flange interface, it ensures unwavering Signal Integrity and high power capacity up to 800W for mission-critical Signal Defense platforms.
