How to find a suitable signal jammer? 


Most client bought a cell phone signal jammer, but they found they can't use it. There are some reasons, first, the frequencies are wrong. This is very important, before you order a wireless signal jammer, you must know the signals you want to block. If we don't do the frequency you want, then the signal jammer can't block it. Second, the power isn't enough, so the jamming radius is very short or even no block, many clients claims that the signal jammer no works, such as portable signal jammer. As you known, the power for a portable blocker is very small. Usually 0.5~1 watt each band, if the signal strength is very strong in the local place, so the jamming radius is very short. Sometimes maybe 0.5m radius, it isn't the cellular jammer problem. When you check the jamming radius, you can see always depends on the signal strength. In this case, you need to use a powerful jammer.
