Description & Specification
8.2 GHz to 12.4 GHz WR-90 E-Plane Sectoral Horn Antenna
Model: WI-90-UBR-15E | 15 dBi Fan-Beam | X-Band Surveillance
The WI-90-UBR-15E is a precision-engineered X-Band Sectoral Horn Antenna professionally flared in the E-plane to deliver specialized Fan-Beam characteristics. Operating within the 8.2 GHz to 12.4 GHz spectrum, this antenna produces a highly focused 16° H-plane beam while maintaining an expansive 110° coverage in the E-plane. It is an essential instrument for radar imaging, sectoral surveillance, and high-intensity EMI/EMC Testing where vertical coverage and horizontal resolution are critical.
