The LGSh-711 product 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 1x
CDMA-800
AMPS/N-AMPS/D-AMPS-800/CDMA-800
The LGSh-711 cellular jammer is available in two versions: LGSh-711 (basic) and LGSh-711M. The differences between the versions are that they operate in different cellular ranges. The LGSh-711 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 operating principle is to generate 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 output connector of the SR50-73 type (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.
Operating frequency range of the IMT-MC-450 standard not less than 462.5...467.475 MHz Operating frequency range of the AMPS/DAMPS800 standard not less than 869...894 MHz Operating frequency range of the GSM900 standard not less than 935...960 MHz Operating frequency range of the DSC/GSM1800 standard not less than 1805...1880 MHz Effective suppression radius 3...50 m Maximum output power at the antenna connector 33 dBm Output power adjustment range at the antenna connector not less than 13 dB (20 times) Operating temperature range +5...+40 C Power consumption not more than 20 W Power supply 220 V, 50 Hz Mean time between failures not less 10000 h.
