The PKI 1680 Handheld Direction Finder is a sensitive radio frequency monitoring device to determine the position of GSM/ UMTS/ LTE mobile phones when using the PKI 1650 IMSI Catcher. Once a mobile phone is forced to transmit a signal, the PKI 1680 device allows the operator to monitor the radio frequency emission level and thus determine the direction to the target. The PKI 1680 device is quick to deploy and easy to use. The built-in Li-ion battery provides the necessary power supply.
The PKI 1680 Handheld Direction Finder is controlled by an Android smartphone application via Bluetooth. Versatility is provided by three different antennas and the adjustable amplifier. PKI 1680 is operated in a user-friendly graphical user interface (GUI) on a robust Android smartphone. This ensures unobtrusive operation in today’s environment. The signal level is both displayed on the screen and provided as audio output for stealthy operation.
