Description & Specification
18.0 GHz to 26.5 GHz WR-42 E-Plane Sectoral Horn Antenna
Model: HS-042-UBR-15-NA | Fan-Beam Radiation Pattern | 500W High Power
The HS-042-UBR-15-NA is a precision-engineered WR-42 E-Plane Sectoral Horn Antenna professionally designed for high-fidelity wide-horizontal illumination. Operating within the 18.0 GHz to 26.5 GHz spectrum, this antenna is expertly flared in the E-plane to deliver a distinct Fan-Beam radiation pattern (77° H-plane x 16° E-plane). Featuring a direct waveguide input with a standardized UG-419/U (UBR) flange, it ensures low-loss power transfer for high-intensity applications up to 500 Watts (CW). It is an essential instrument for EMI/EMC Testing, wide-area surveillance, and precision antenna characterization.
