Description & Specification
15.0 GHz to 22.0 GHz WR-51 H-Plane Sectoral Horn Antenna
Model: HS-051-UBR-10-NA | Fan-Beam Radiation Pattern | 500W Power
The HS-051-UBR-10-NA is a specialized WR-51 H-Plane Sectoral Horn Antenna expertly engineered for wide-vertical illumination requirements. Operating within the 15.0 GHz to 22.0 GHz frequency range, this antenna features a precision sectoral flare in the H-plane to create a distinct Fan-Beam radiation pattern (16° H-plane x 100° E-plane). Equipped with a direct waveguide input and a standardized UBR flange, it ensures high-efficiency power handling up to 500 Watts (CW). It is an essential instrument for EMI/EMC testing, broad-area surveillance, and precision radar calibration.
