Multi-band cell phone signal jammer can work to isolate the specified unwanted frequency bands when there is the demand for signal free zone. The Newest 8 Antennas 4W Handheld Selectable Cell Phone 3G 4G Jammer WIFI GPS Jammer.Selection Frequency is one of the multifunctional signal blocking units available with well-built compact construction and delicately combined functionality.
The powerful jammer has a wide affected frequency ranges to include CDMA/GSM, DCS,3G,4G LTE, 4G Wimax,GPS,Wifi. It also has a jamming range up to 20m, depending on the signal strength in the given area. Within the range, just turn on the jammer, all wireless connection to 2G, 3G, 4G or Wifi,GPS Lojack network will be disabled at the same time. Also, the jammer is a selectable unit. In other word, user can choose to allow operation of one or a few of frequency bands. Adjustment of ON or OFF any of the single bands will not cause any disruption to the operation of others.
