ZD-GR050 Portable Anti-Bomb Jammer

The jammer uses an advanced technology called automatic digital interference code technology. This jammer can jam all kinds of wireless communication within 20 to 6000MHz. It classifies standards of different signal and jams them by using corresponding optimal methods which achieves the best jamming effect. It overcomes common weakness of jammer from other companies such as weak jamming effect for walkie-talkie or 4G signals. The advanced technology also makes jammer use low power to cause long jamming distance. It reduces damage of high temperature and strong high frequency radiation on passengers’ health markedly.

Generally, this jammer uses low power to cause jamming effect much better than expectation. It keeps effectiveness of jammer and protects users from large radiation. And the device has small volume and light weight makes it flexible and reliable.

This jammer can be widely used by departments of police, antiterrorism and country security protection.

◇ It can prevent activation of remote controlled bombs and stop the terrorism activities.

◇ For the emergency security protection during mass disturbances and large meeting, it can block the mobile signal in a large range to stop the extension of turbulence.

◇ When it is used in important department of country security and military, it can block mobile phone signal;

◇ To protect public security of some scenes, it can block wireless communication.

◇ When it is used in scenes of illegal gambling or sell drug, it can block mobile phone signal to stop the communication between criminals.

◇ When it is used in important department of country security and military, it can block wireless signal.


◆ It applies one of the most advanced interference technologies called automatic digital interference code technology. With this technology, the jammer has advantages of high interference efficiency, long interference distance and low total output power (Total output RF power is less than 150W),light total weight(main device(include battery inside) is less than 26Kg). The volume of this useful machine is small so that it is easy to be carried and moved.

◆ It can jam signals of all the required bands effectively. The interference efficiencies for different bands are almost same. The jamming effect of ZD-GR050 would not be reduced by weakness in some frequency bands like jammer of other companies.

◆ It can also jam signals in individual band.

◆ It has functions of displaying work state (band, output power, battery percentage), error warning (overpress, underpress, overheat) and so on.

◆ It has handheld LCD displayer to display data, status and remote control signal transmission of each frequency band.


◆ Frequency band:20-6000MHz—include remote controller, walkie-talkie, 2G、3G、4G、WIFI and other signals;
