Small – Power Portable DSS Multi-Band Jamming System
Model: HJ21B
HJ21B Stationary Mobile Phone Jammer with FRS to jam all kinds of mobile phones’ signals. HJ21B can jam AMPS, N-AMPS, NMT, TACS, GSM, CDMA, TDMA, iDEN, UMTS, FRS and HJ21B has dip switches to adjust the output power per band. The jamming distance of HJ21B Stationary Mobile Phone Jammer with FRS is radius 10M
HJ21B jamming noise signal source using the power amplifier to generate the environment use DSS Jamming System, continuity. Within the scope of its influence and interference signals will be suppressed vertically down the signal of the network service providers and telecommunications. The signal is much stronger interrupted connection lost phone waves. Lost phone waves can not be conducted through communication that ensures safety information is not transmitted over telephone lines. Equipment also use more scanning module detects the mobile phone to contact parts can activate signal suppression effects
