Wideband Direction Finding System

PKI 4390Print

This computer-controlled direction finding system can be installed stationary or also mobile just as the antennas required for direction finding. The standard frequency ranges from 20 MHz up to 3 GHz. Other frequencies are optionally possible, too. The PKI 4390 enables quick and exact direction finding of HF signals. A receiver unit is integrated to evaluate the received HF signals in order to perform simultaneous direction finding over a wide frequency range. Different possibilities to display the transmitter positions are available, such as digital maps or common internet map services. If more than one system is available, automatic cross bearings can be performed. This allows for automatic radio monitoring of large areas to identify HF signals of all kinds.
