FT-RF WR650 Waveguide Input Antenna feature direct WR650 rectangular flange feeds across L-band spectrums (1.12 GHz to 1.70 GHz). Manufactured from high-strength structural aluminum with internal support ribbing, they provide accurate gain calibration standards for GPS/GNSS receiver testing, DAB broadcasting, and L-band aviation radar installations.

Engineered with high polarization purity and standard CPR650F cover flanges, WR650 input horns deliver stable directional beams and minimal backscattering across demanding anechoic chamber and outdoor field environments.
