FT-RF WR2100 Standard Gain Horn Antennas (HS Series) are extra-large reference calibration standards engineered for low-frequency VHF/UHF EMC chamber calibration and high-power radiated immunity setups (350 MHz to 530 MHz). Featuring standardized 10, 15, or 20 dBi gain options, they are assembled with an integrated waveguide-to-coaxial adapter for direct cable connection.

Manufactured from high-strength structural aluminum, the WR2100 HS series guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness, providing exceptional physical stability under high continuous power handling while ensuring highly repeatable calibration results.
