FT-RF WR650 Standard Gain Horn Antennas (HS Series) provide precise calibration standards across lower UHF and radar surveillance spectrums (1.13 GHz to 1.72 GHz). Featuring standardized 10, 15, or 20 dBi gain options, each horn features an integrated low-loss coaxial adapter interface for direct instrumentation connectivity and radar systems testing.

Engineered from premium structural aluminum alloys, the WR650 HS series guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness, delivering high mechanical strength and stable gain response for demanding low-frequency testing environments.
