FT-RF WR1800 Waveguide Input Antennas delivers direct WR1800 rectangular flange feeds across VHF/UHF transition spectrums (410 MHz to 620 MHz). Featuring heavy aluminum framing with integrated crane lifting attachments, these large-scale horns ensure safe rigging and precise positioning in large anechoic chambers.

Constructed from heavy structural aluminum with internal support ribbing, the WR1800 WI series provides high mechanical rigidity and predictable gain performance for low-frequency EMC radiated emissions testing and defense broadcast calibration.
