FT-RF WR75 Standard Gain Horn Antennas (HS Series) integrate a calibrated Ku/X-band pyramidal horn with a precision waveguide-to-coaxial adapter (10.0 GHz to 15.0 GHz). Featuring standardized 10, 15, 20, or 25 dBi gain options, they serve as primary reference standards for maritime radar testing, VSAT terminal calibration, and EMC chamber validation.

Crafted from aircraft-grade aluminum alloy, the WR75 HS series ensures high cross-polarization rejection (>30 dB) and smooth gain flatness across its entire operational bandwidth.
