FT-RF WR770 Waveguide Input Antennas feature direct WR770 rectangular flange feeds across Sub-1 GHz and UHF spectrums (750 MHz to 1.12 GHz). Constructed from heavy-duty structural aluminum with internal support ribbing, they deliver accurate gain calibration standards for Sub-GHz IoT protocol testing, UHF TV broadcasting, and EMC radiated immunity test setups.

Engineered for high structural stability and low backscattering, WR770 input horns come equipped with CPR770F cover flanges and rigging attachments for safe positioning in large anechoic chambers.
