Active Horn Antenna

The AHA-118 is a broadband, linearly polarized Double Ridge Horn Antenna with built-in, 40 dB gain, low noise preamplifier. This active antenna operates over the frequency range of 700 MHz to 18 GHz, with excellent efficiency from 1 GHz to 18 GHz. This measurement system arrangement, with preamplifier directly behind the antenna, rather than next to (or embedded into) the remotely located test receiver, increases measurement sensitivity, as well as accuracy, by amplifying the received signals prior to being significantly attenuated by the long cable run between the test site and test equipment area.
