FT-RF WR229 Standard Gain Horn Antennas (HS Series) deliver high-precision reference gain standards across S-band radar surveillance and 5G N77 spectrum testing setups (3.22 GHz to 4.90 GHz). Featuring standardized 10, 15, 20, or 25 dBi gain options, they provide clean, low-reflection signal coupling for S-band radar systems and 5G sub-6GHz testing.

Fabricated from passivated aluminum alloy, the WR229 HS series guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness, combining physical robustness with environmental durability.
