Drones Becoming More and More Powerful

Anyone can buy a drone that can carry up to 10 pounds and fly several miles through  the internet or in any local electrical goods store.
Using a GPS control system and autopilot, many of these small aircraft are able to fly programmed routes on their own without a pilot.
High Power Full Band Vehicle Military Convoy Protection Roof Mounted Jammer System
MAX total output power can be set up to 1000W.
12 bands in total (every band is with 1 individual module) can cover all useful frequency signal between 20MHz - 6GH
WF-12 JAM is a  High Power DDS Convoy Jamming System, implementing the most effective and reliable RF jamming technology and equipped with a fully-integrated broadband jamming system.

- Designed with ultra broadband frequency bands, 20MHz-3600MHz (20-6000MHz).
- 12 modules plug and play design, facilitate for future power upgrading, change and maintenance. Any ruin on the modules never interfere the normal operating of other modules.

Protecting military and VIP convoys from the threat of Remote Control Improvised Explosive Devices (RCIEDs)-road-side bombs has become a challenge and task in many parts of the world.

Tangreat solutions-WF-D12 JAM, High Power DDS Convoy Jamming System, implementing the most effective and reliable RF jamming technology and equipped with a fully-integrated broadband jamming system.

WF-D12 JAM can cover, continuously and simultaneously, all the RF communication Frequencies 20MHz~3600MHz (20-6000MHz) which are most commonly used by terrorists to detonate road-side bombs (RCIEDs).Adopting the latest jamming technologies, WF-D12 JAM features ultra-high RF transmission power of 1300 watt, making a bigger shielding range around the vehicle. Beyond the installation of the convoy protection device itself, the vehicle is customized with special RF protection for full protection of the driver and passengers. System management, including activation and control and operation is carried out through a wired remote control unit installed covertly inside the driver’s console unit.

Once the system is activated, it transmits unique noise signal which creates "Firewall" between the transmitter (terrorist) and its receiver (explosive device). Effective eighteen-month warranty and technical support is absolutely indispensable to make sure our excellent quality and reputation.

There is absolutely no better way to defend the threat of radio-activated bombs.
Protect military and VIP team from the road-side remote improvised explosive device (RCIED) attack detonated by the terrorists. Moreover, It can prevent terrorists using GPS location to track the vehicles efficiently.

Used for EOD. Before EOD, wireless telecommunication signals surrounding the bomb must be blocked effectively to prevent the terrorists detonating the the bomb through the wireless remote control devices and avoid the huge casualties.

It can be  applied that the common used telecommunication frequency will be blocked when the Police arrest the criminals in order to prevent the criminals gang or Police insider leaking the confidence through the wireless equipments ,so that the arrest collapsed. It also make the criminals not be able to remotely control the bomb in the key entrance of the building so that Police can quickly access to the building and round up the criminals to avoid the casualties.

Protecting the boarder and army patrol from the attack of road- side bomb RCIED  denotated by the terrorists.

It can be used to prevent terrorists remotely controlling the bomb bursting points in military protection zone,government buildings and some other important places. It can also make the criminals hidden in the military protection zone not communicate with the outside gang to leak the confidence.

In the event of the partial ground war, this wireless jamming system can prevent the enemy laying the bomb denotated by the wireless remote control in advance. In order to protect the land surface chariot attacking troops, tank and soldiers’ lives.

It can also fixed in some occasions for a temporary protection to respond to some emergencies.
