FT-RF WR187 Standard Gain Horn Antennas (HS Series) offer accurate, repeatable gain calibration for lower C-band satellite transponder systems and terrestrial microwave backhaul links (3.95 GHz to 5.85 GHz). Featuring standardized 10, 15, 20, or 25 dBi gain options, they combine a pyramidal horn body with an integrated low-loss coaxial adapter feed.

Manufactured from heavy-duty machined aluminum with protective anodized finishes, the WR187 HS series guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness, maintaining structural integrity under continuous high CW power inputs.
