Double Ridge Active Horn Antenna

Model: AHA-840

18 - 40 GHz

Horn Antenna with Built in Preamplifier

Active Horn Model AHA-840

is part of our extensive line of EMC test antennas. The AHA-840 smartly incorporates a with a precision waveguide to coaxial adapter (meticulously tuned as a set for optimum VSWR performance and impedance matching) and a broadband, high-gain, low noise preamplifier; integrated into a single, well-built, durable, custom designed assembly which facilitates the flexibility to be configured for almost any application.
