FT-RF WR28 Standard Gain Horn Antennas (HS Series) integrate a calibrated pyramidal horn with a low-loss waveguide-to-coaxial adapter across Ka-Band (26.5 GHz to 40.0 GHz). Featuring standardized 10, 15, 20, or 25 dBi gain options, they provide precise reference standards for 5G FR2 mmWave antenna measurements and EMC testing.

Crafted from high-grade aluminum alloys, the WR28 HS series guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness across the full operational bandwidth. Each antenna is designed for effortless connection to laboratory instrumentation.
