Product Overview

RENT COM POWER AHA-118 Double Ridge Guide Horn Antenna (Call for Availability)

The Com Power 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.

Each antenna is individually calibrated per ANSI C63.5 or SAE ARP958 with NIST traceability. The Com Power AHA-118 is designed to be extremely durable, making it an ideal choice for daily use in laboratory environments. The AHA-118 can easily be configured by the operator on the fly, as necessary, to meet the specific requirements for the task at hand. Where system sensitivity (large signal to noise ratio) is not the primary concern; attenuation, notch or bandpass filters can be inserted between the antenna and preamplifier, in order to facilitate measurements in the presense of highamplitude signals. Or, the preamplifier can be bypassed altogether, in which case the antenna can be used for receiving or transmitting purposes.
