The PERSONAL RNM & V2K EMF JAMMER (or Personal Signal Jammer) : Our store extensive researches into EM weaponry and EM harassing devices (and Radionics), such as EM jammers and EM zappers. "Signal Jammer" is also referred to as: Signal zapper, signal blocker, signal scrambler, signal crammer, signal obstructor, signal squasher, signal destroyer, signal deactivator. TMJ-type devices, as with all RF transmitting devices we design and build, is based on our RF policies defined on our policies webpage ( policies.htm ). The TMJ is designed to send out strings of pulses in a narrow bandwidth ( selected center freq 1MHz - 3GHz; BW is 0.1% center freq or 10KHz, whichever is greatest ) designed to jam ( within the immediate area of one's body ) offending EM transmitters, surveillance devices, microwave controllers, et al - even the newest EM devices. Portable and worn or carried on or near the body. Note that EM signal jammers are never designed to operate as electronic weapo
