Description & Specification
WR-51 E-Plane Sectoral Horn Antenna
Model: HS-051-UBR-15-NA | 15.0 - 22.0 GHz | 15 dBi | Fan-Beam
The HS-051-UBR-15-NA is a precision-engineered WR-51 E-Plane Sectoral Horn Antenna designed for specialized wide-angle illumination. Operating across the 15.0 GHz to 22.0 GHz frequency range, 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 UBR Flange, it ensures high-efficiency power transfer up to 500W. Manufactured from high-grade aluminum, it is the ideal instrument for EMI/EMC Testing, wide-vertical beam scanning, and precision antenna gain measurement in both laboratory and field environments.
