XLG15 is the unique 4G jamming device developed by Swedish signal blocking specialists. It is carefully designed for precise jamming of specifically selected frequency bands of 4G, XM and LoJack..

This LoJack XM Radio 4G cell jammer is absolutely reliable when it comes to jamming the signals of LoJack trackers, XM radio bands and 4G devices. This 4G signal blocker may become a perfect jamming device when combined with GPS/GSM Jammer because of wide frequency coverage and ability to block signals of all types of trackers along with probably all types of cell phones.

XLG15 is the LoJack XM 4G cell phone jammer and because it works against such special frequencies it stands apart from other products we have. This handheld device has few purposes. The main thing it does is that it helps you to get rid of LoJack tracking. All LoJack tracking devices use low frequencies to track their object. Commonly it is used to locate bikes and laptops, yet nowadays it is also used to track any kind of vehicles sometimes.

The next thing that can be handled by XLG15 is 4G frequency. This advanced communication band is used in many potentially dangerous appliances like Femtocell devices which establish connection between wireless devices in your house via 3G and 4G frequencies. Yet Femtocell device can be used by law enforcement agencies for eavesdropping of your mobile phone calls or to track your own location when you are at home. But this 4G jammer can protect your privacy from such rude intrusion.


The last thing is an XM frequency. It is a satellite radio with a lot of entertainment shows, music, news, etc. Many students adore listen to this satellite radio while they are at their lectures. Teachers and professors don't want their students listen to them during the lectures and this device can help them to improve the discipline inside classrooms and lecture halls.

XLG15 is your reliable and powerful LoJack XM Radio 4G Signal Jammer. It may be used as long as you need it because of great cooling system and ideally tuned frequency bands. Although selected frequencies are rare you still can jam all of them using this awesome 4G cell jammer.

    That jammer is exactly the same as I was looking for for a pretty long time. You see, there are literary billions of various mobile phone jammers, Wi-Fi blockers and other stuff, but it is really hard to find a signal blocker with such specific frequencies. That site was not the only one, where I've found it, but it looked OK for me, so I've decided to give a try. Fully satisfied with the results!

    That jammer is my solution for LoJack tracking problem. My boss gave me a notebook, that is my working tool, and I definitely know that there is a LoJack tracker in it. So, I've decided to use that jammer to block it. If I'll lose it or the notebook will be stolen – it will be able to track it, but when I'm working, tracking is distracting me.

    I’ve bought that jamming device two months ago and I use it mostly to block the 4G. My students often use that network to look for answers at Google while writing the exams, one day I got really tired of that and took that jammer. It works great and it doesn’t block mobile phones, which is cool for me, I don’t need problems with parents of my class, I just want fair exams.

    I think it is a nice gadget. It blocks everything I need, LoJack for tracking, satellite communications and the fourth generation of mobile communications, the Wi-Max standard if to be exact. I use it together with a small GSM jammer and they work perfect together. The only negative issue of this jammer is that that the last antenna is pretty long and it is not really convenient to attach the device at your belt, so you have to carry it in your hand all the time.

    I have bought this jammer to avoid LoJack tracking bug that was surely installed in my bike. I do not want anyone to track me travelling the country, because I am a free man. What about security? I think that Benjamin Franklin was right when said: "Any society that would give up a little liberty to gain a little security will deserve neither and lose both".
