Description & Specification
1.14 GHz to 1.73 GHz WR-650 L-Band Standard Gain Horn Antenna
Model: HS-650-UDR-20-NF | 20 dBi Gain | 1000W High Power
The HS-650-UDR-20-NF is a high-power L-Band Standard Gain Horn Antenna professionally engineered for the WR-650 standard. Operating within the 1.14 GHz to 1.73 GHz spectrum, this antenna system integrates a precision waveguide-to-coaxial transition with a durable Stainless Steel N-Female interface. Delivering a consistent 20 dBi gain and capable of handling up to 1000 Watts of continuous power, it is the premier radiator for EMI/EMC testing, Signal Defense operations, and precision antenna gain measurements in laboratory and tactical field environments.
