FT-RF WR2300 Standard Gain Horn Antennas are ultra-large-scale reference calibration standards designed for low-frequency Sub-1 GHz and VHF testing down to 320 MHz (320 MHz to 490 MHz). Each unit combines a massive pyramidal horn with an integrated high-power coaxial adapter assembly.

Built from heavy-duty structural aluminum with reinforced ribbing and rigging fixtures, WR2300 horns maintain structural integrity for physical apertures exceeding 1.5 meters while delivering accurate gain calibration.
