DJ-25 jammer is a dedicated part of ARM-28 upgrade
kit for jamming and neutralizing Unmanned Aerial Ve-
hicles (UAVs). It includes a high-power signal genera-
tor (up to 52dBm) and powerful helical antennas with
a gain of 21-28dBi. The system provides the ability to
instantly and completely cutoff the UAV from the ope-
rator by jamming the 2.4 and 5.8GHz frequency and
geolocation systems in GPS, Galileo and GLONASS
systems.
Optional, the DJ-25 system can interfere with GSM
signals in the 850-900MHz band, ensuring interfering
of UAVs working in this frequencies, as well as, neu-
tralization of Improvised Explosive Devices working
based partly on mobile network.
The ARM-28 modernization package was selected by
NATO user in both land and naval versions. The first
contract was signed in 2021. Deliveries were comple-
ted on time, allowing the user to dramatically incre-
ase anti-aircraft capabilities. The ARM-28 with DJ-25
jamming system was already tested and ordered by
a NATO user.
