Product Description
High Power Portable Cell Phone Signal Jammer


NameHigh Power Bomb Signal Jammer
TypePortable Jammer

HDT-201B50 is the HIGH POWER portable Remote-Bomb & Cell Phone/Wi-Fi jamming system, implementing the most highly effective and extremely reliable signal jamming technology. By cutting off the data transmission of wireless signals of all kinds, 201B50 can protect military, police and VIP convoys from the threat of Remote Control Improvised Explosive Devices (RCIEDs) and road-side bombs.
HDT-201B50 is also a state-of-the-art efficient cellular/Satellite mobile phone jammer, which is designed for bomb disposal security applications, like Troop marching and filed operation. The jammer is constructed to block continuously and simultaneously up to six frequency bands. Simultaneously jam most of the existing VHF/UHF communication (Walky-talky) stands (Frequency bands) around the world, as well as garage, door remote controls, car alarm systems and hand made radio emitters and so on.

HDT-201B50 Jamming System can block (jam), continuously and simultaneously, all the wireless communication frequencies from 20MHz to 3600MHz or from 20MHz to 6000MHz, which are commonly used by terrorists to detonate road-side bombs (RCIEDs). Adopting the cutting-edge signal jamming technologies, 201B50 features ultra-high RF transmission power of 300 watt, making a large shielding range around the jammer. 
201B50 has 6 sets of jamming signal generators inside, which can transmit highly effective jamming signals targeting all VHF/UHF, cell phone and Wi-Fi devices within the blocking range.

Once you turn the jammer on, with the help of its high-gain omni-directional antennas, 201B50 can jam continuously and simultaneously, all the RF communication frequencies 850MHz~2660MHz which are most commonly used by cell phones and Wi-Fi devices.

It is constructed to jam continuously and simultaneously up to 6 frequency bands. Its smart active cooling system enables non-stopped use even in a very hard climatic and weather condition.

The user-friendly system is integrated into a trolley type weatherproof and shockproof pelican case1560.Frequency bands include all the cellular phone system or Satellite system optional.

Once the system is activated, it transmits unique noise signal which creates "Firewall" between the transmitter and its receiver (walkie-talkies, cell phone and Wi-Fi devices).
