FT-RF WR770 Standard Gain Horn Antennas (HS Series) provide heavy-duty, calibrated reference gain standards across Sub-1 GHz IoT testing, UHF TV broadcast calibration, and EMC radiated immunity test setups (750 MHz to 1.12 GHz). Featuring an integrated waveguide-to-coaxial adapter with N-type female connectors.

Fabricated from heavy-duty structural aluminum with internal support ribbing, the WR770 HS series maintains precise physical geometry and predictable gain performance for large-scale low-frequency measurements.
