FT-RF WR42 Standard Gain Horn Antennas (HS Series) integrate a calibrated pyramidal horn with a low-loss waveguide-to-coaxial adapter across K-Band (18.0 GHz to 26.5 GHz). Featuring standardized 10, 15, 20, or 25 dBi gain options, they provide precise reference standards for satellite communication testing, radar cross-section measurements, and EMC emissions testing.

Fabricated with high-grade gold-chem-film coated aluminum, it delivers consistent half-power beamwidths, low side lobes, and exceptional polarization purity. Fully compliant with standard IEEE antenna calibration procedures.
