RCIED Jammer is a wide-band Vehicle jamming system, designed for the protection of VIP’s and groups of people from radio controlled improvised explosion by disabling the radio exploder control lines in dangerous areas and for the prevention of leakage of information through intercepting units during confidential talks. RCIED Jammer transmits RF interference and creates a "Radio Frequency Protected Zone" around the object that prevents remote controlled bomb activation by various RF means in its vicinity with a sufficient jamming safety radius, in order to save lives and prevent serious injuries. RCIED Jammers are also deployed to guard forces in the field, Dignitaries and VIP’s, checkpoint and border rossings, roadblocks, Embassies, Police and Government offices etc. RCIED Jammer are available in various models as per the frequency and output power. However these jammers can be customized as per the user requirements.

System Features
Modular design, independent work between modules, more efficient performanceSegmented block, jamming downlink signal only, do not affect operator uplink signals, to ensure the validity of the signal block, and also no harm to human bodyFrequency band can be customized according to the needs of users, including GSM, CDMA,GPS,DCS, PHS 2.4G,3G, 4G, 5.8G and other wireless communication equipment including mobile phone signal, uav signal, WiFi, bluetooth, Walkie-Talkie and other wireless communication equipmentDirectional antenna or omni-directional antenna can be selected according to actual use requirements. The antenna is connected with the host via corrugated cable, with fixed interface for easy disassembly.The shell of the whole machine adopts aluminum alloy wiredrawing shell to ensure the heat dissipation and effectively improve the isolation degree between each module. At the same time convenient installation, all kinds of vehicle models can be installed.Built-in metal industrial switching power supply ensures the service life and jamming effect of the equipment. Can ensure continuous uninterrupted work for more than 3 years, the maximum extent to ensure the service life of the equipment, ensure that each channel has enough bandwidth power, to ensure the jamming effect.
