FT-RF WR1800 Standard Gain Horn Antennas (HS Series) deliver calibrated reference gain across VHF/UHF transition bands (410 MHz to 620 MHz). Featuring standardized 10, 15, or 20 dBi gain options, these large-scale horns are ideal for low-frequency EMC radiated emissions testing and defense broadcast calibration.

Constructed from heavy aluminum framing with integrated crane lifting attachments, the WR1800 HS series guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness, ensuring safe rigging and precise positioning in large anechoic chambers.
