Description & Specification
WR137 C Band Waveguide Horn Antenna (Model: WI-137-UAR-15)
5.85 - 8.2 GHz | 15 dBi Gain | Compact 360g Design
Weighing a mere 360g, the WI-137-UAR-15 redefines portability in C Band testing. This precision aluminum horn covers the 5.85 to 8.2 GHz spectrum, striking a perfect balance between physical size and performance with a 15 dBi gain. Despite its compact footprint (114x144x176mm), it is engineered to handle substantial power loads of up to 800 Watts. The integrated UAR flange ensures direct compatibility with standard waveguides, making this model an agile choice for dynamic EMI/EMC setups where space and weight are critical factors.

Key Features (Model Specific)
Featherweight Construction
At only 360g, this is one of the lightest C Band horns available, ideal for portable tripods and rapid field deployment.
Balanced 15 dBi Gain
Provides a broader 30°/29° beamwidth compared to high-gain models, allowing for wider area coverage during scans.
Compact Form Factor
Dimensions of 114x144x176mm allow for integration into space-constrained chambers where larger horns won't fit.
High Power-to-Size Ratio
Despite its small size, it robustly handles 800 Watts, ensuring reliability in high-energy transmission tests.
UAR Flange Interface
Equipped with a standard UAR flange for secure, leak-free connections to WR137 waveguide systems.
