Description & Specification
WI-159-A1-20 C Band Waveguide Horn Antenna
Precision WR159 Aperture Radiator | Multi-Standard Flange Interface | 4.9 GHz – 7.05 GHz
The WI-159-A1-20 is a high-precision, laboratory-grade WR159 Waveguide Horn Antenna expertly engineered for directional RF testing across an extensive 4.9 GHz to 7.05 GHz C Band spectrum. This premium aperture antenna features an optimized pyramidal geometry to achieve stable directional radiation profiles, delivering a robust nominal gain of 20 dBi with minimum side-lobe interference. Meticulously manufactured from high-grade lightweight aluminum in Taiwan, its ultra-lightweight 0.6 kg structural layout minimizes mechanical stress on positioners and tripod arrays while maintaining excellent thermal and structural leveling. Equipped with a highly versatile UAR Flange interface, it ensures seamless mechanical coupling with UDR58, UER58, CPR159F, and CMR159 waveguide sub-systems. It serves as an indispensable reference instrument for telecommunications validation, satellite link monitoring, and critical microwave anechoic chamber measurements.
