  • SMO-CT Software Package for Digital TV Signal Analysis

Probabilistic spectrum of Wi-Fi and GSM signals, and selective direction finding of DECT signal

Automatic localization of RF emitter in Map mode

The antennae of ARC-A3A can be used both in active and passive mode. The design of the handle and antenna elements enables detection of RF emitters with vertical and horizontal polarization. The handle is optimized for operation in the field conditions. The weight of the handle with the antenna is 800 gram max., the center of gravity is located below the palm level thus enabling to work longer without getting tired.
