Units of the SAJ series are being used by officials, official security organisations and the military as a means for defending against hazards associated with the fight against terrorism. Operational areas range from suppression of communications over GSM paths while fighting organised crime to preventive measures for neutralising remotely-activated explosives associated with assassination attempts.
The signal radiated by an SAJ unit jams remotely controlled receivers, preventing execution of coded command transmissions by third parties. Devices outside the protected area remain unaffected.
Each SAJ is specifically designed to jam those downlink cellular signals associated with the country of use. The SAJ can simultaneously jam single, dual and tri-band cellular systems and is available in versions having various power outputs. Its robust construction renders it especially suitable for implementation in harsh operational environments.
Using specially coded transmissions, the SAJ units deceive the receivers of GSM mobiles, preventing them from receiving calls from their base stations. SAJ types are versatile, being offered for varying applications having varying output power classes. In addition, the units are also available in dual and triple band versions. The radiated power of the SAJ units lies within the range of conventional portable or mobile radios, thus physiological detriment to users is not to be expected.
All units are supplied with a clear, userfriendly display indicating battery charge, radiated power and operational mode. Built-in Ni-Cd accumulators are charged with a builtin charger. The SAJ units can also be powered from an external source if continuous operation becomes necessary. Their small dimensions allow these units to used in a discrete manner. A version with attache case including integrated antenna is available for covert operations. The SAJ protected zones can be extended for wider geographical coverage by simply adding more devices on a chain basis.
Features
Compact size
Rugged, all weather construction
Simple operation
Adjustable power output
Unobtrusive installation
High performance, excellent value
Plug-in frequency modules
Optional model with custom jamming waveforms or frequency ranges
Band 1: GSM-900 (925 – 960 MHz)
Band 2: GSM-1800 (1805 – 1880 MHz)
Single band operation or simultaneous multi-band
Blocking range
Approx. 100 m. Protection area is influenced by the distance
to the nearest cell base-transmitter. If the target area is close
to a cell base station, additional signal power may be needed
to ensure corruption of the incoming signal.
