The LGSh-701 jammer is designed to block (suppress) communication between base stations and user terminals of cellular networks operating in the following standards:
IMT-MC-450(NMT-450i) GSM900 E-GSM900 DSC/GSM1800 DECT1800 CDMA2000 1х CDMA-800 AMPS/N-AMPS/D-AMPS-800/CDMA-800 The LGSh-701 cellular jammer is available in two versions: LGSh-701 (basic) and LGSh-701M. The differences between the versions are that they operate in different cellular ranges. The LGSh-701 product in the M modification blocks the operation of AMPS/N-AMPS/D-AMPS-800/CDMA-800 networks instead of the IMT-MC-450 standard.
The jammer operates by generating a noise signal that is fed to the antenna outputs. The device has three outputs and, accordingly, three antennas. Smooth adjustment of the radiation power is possible for each output. The use of a standard SR50-73 output connector (analogous to BNC) with a wave impedance of 50 Ohm allows the use of external antenna devices both to increase the suppression range and to form the required shape of the suppression zone separately for each frequency range.
The product can be used to block the operation of unauthorized wiretapping devices created on the basis of cell phones of all the above standards.
