ARTIKUL-D11
Portable Automatic Direction Finder
Purpose:
- Direction finding, recording, technical analysis and classification of signals used in modern communication systems and data transfer system in HF, VHF, UHF and SHF ranges, as well as localization of their emitters. The last function is provided when the direction finder works as a part of mobile stations.
