To isolate all signals including cell phone, GPS, Wifi, 3G, 4G LTE and 4G Wimax as well with single one full-functional wireless signal jammer actually become reality with the rapid progress of jamming technology. Check out this Adjustable 20 watt 8 Antennas High Power GPS/ WiFi/ 4G(LTE+Wimax) Jammer newly released here.


The jammer is a high performance unit featured with multi-functions, durability, efficiency and wide jamming range. Just turning on the 8 bands frequency jammer, users can easily disable all mobile phone, GPS enabled devices, Wifi networks etc. The TX frequency covers down link only and will not affect the base station at all. The jamming range reaches up to 40m depending on the signal strength in the given area, enough to be used in many serious wide locations like hospitals, factories, office building, concert halls and so on. The high power jammer can flexibly be used in car with a DC12V car charger or any other sites using powerful AC adapter. Besides, the unit can provide a lasting continuous jamming service with well-designed construction and excellent cooling system. The jamming capability is supported with 20W high power along with 8 high gain omni-directional antennas.



● The latest design and Good cooling system with cooling fan inside.

●Use stronger and longer External Omni-directional antennas,all the TX frequency covered down link only.

●Could be used in car directly,With DC12V car charger.

●Can adjust or turn off any single band without influencing the other bands operation.

●Totally with a 20 Watt high output power makes a more efficient jamming.

●Jamming range:20-50 M@-75DBM (the jamming radius still depends on the signal strength in given area.)

● ODM and OEM orders are welcome.
