Reviews: Adjustable 3G 4G(4G LTE + 4G Wimax) Cell Phone Jammer - 40M

Rating: recommend rating
That signal jammer is a really powerful device. And it is possible to choose what to jam and even tune the interference signal power. I use it for blocking Wi-Fi snooping, just don't want my Wi-Fi network to be seen form the outside. The only thing it lacks is the cooling system, it is getting rather hot while working, though it never turned off because of overheating.

Wow, guys, that 4G support is really what I was looking for. Now I'll be able to block all mobile phones with a single stationary signal blocker and I won't have to worry about the battery anymore! It will be a great addition to my home security system. And it blocks both LTE and Wi-Max. That means that there will be no video calls and mobile Internet anymore!

I'm running that RCJ40-D for almost a month and I can say that it does its work great! It was bought for the only one purpose - to jam Wi-Fi connections of the executives at my office, because I care about network's security. I've tried to prohibit Wi-Fi but some people still have forgotten to turn off the Wi-Fi module. Now I turn it off myself. I just turn all the antennas except Wi-Fi off and everything works great except Wi-Fi. Thanks!

The power of this device made me to buy it. Massive coverage radius along with adjustable output power of each antenna makes it possible to jam exact frequencies in specified area. I can tune it to jam only one frequency, Wi-Fi, for example and use the other bands freely. Powerful and flexible home shielding device!
