Features:
- Operation at stops and while moving (when the equipment is carried by operator or installed on a vehicle)
- Very low weight and small sizes, fast deployment
- Equipment can be transported by two operators
- Replaceable antenna systems
- Joint operation of several direction finders (when communication equipment is available), e.g. as a part of Automated Spectrum Monitoring Systems (ARMADA, AREAL etc.)
- To prevent overloading of Direction Finder's digital path in complicated electromagnetic environment, digital radio receiver includes additional analogue paths with 500 kHz bandwidth
- Selective direction finding of 2G/3G/4G/5G Base Stations
- Selective (time-slot based) direction finding of subscriber 2G terminals (mobile phones, trackers, etc.), operating at the same frequency
- Selective direction finding of Wi-Fi communication devices with recognition of MAC-address, including those that use non-standard frequency ranges
- Power supply from buit-in batteries, portable electro generator, external AC mains or vehicle on-board DC.
Examples of deployment of ARTIKUL-H1 Direction Finder on a vehicle and fixed workstation are presented in pictures.

Direction Finder Provides:
- Single- and multi-channel automatic direction finding of RF emissions with any modulation type and spectrum width in 1.5 to 8000 MHz range (using replaceable antenna systems)
- Displaying the emitter bearing and localization of detected emitter on the electronic map
- Panoramic spectrum analysis within the entire operating frequency range or within separate intervals under complicated electromagnetic conditions, detection of changes in ambient electromagnetic conditions
- Search for radio emission, measurement of their parameters
- Creation of databases, their extension and comparing of the recorded data with the references in the database
- Recording of radio signals to a storage device
- Recording the radio environment to storage within a specified frequency range. This procedure can function within a long period and is based on amplitude/frequency/bearing/time coordinates, the station location and the absolute time at the time of saving
- Accumulation of data for further analysis in the postprocessing mode
- Decoding of service parameters of communication systems (GSM, UMTS, LTE, 5G, IS-95, cdma2000, EV-DO, TETRA, DECT, DMR, APCO P25, Wi-Fi etc.).
