ARTIKUL-H1

Manpack Automatic Direction Finder

Purpose:

The direction finder is intended for search, detection, automatic direction finding and localization of radio emission sources. The direction finder can be operated at stops and while moving standalone or as a part of automated spectrum monitoring systems (ARMADA, AREAL etc.)

Typical configuration:

Carrying frame to mount equipment of ARTIKUL-H1 with AS-H2 Antenna System and the direction finder with AS-HP1 Antenna System in manpack operation mode

Options:

Features:


Examples of deployment of ARTIKUL-H1 Direction Finder on a vehicle and fixed workstation are presented in pictures.
