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