6 Antenna Selectable Handheld GPS 3G 4G Cellphone Blocker

First of all, the 6 band jammer is a fully functional one for all CDMA/GSM, DCS/PCS, 3G, 4G LTE, 4G WIMAX, and GPSL1. With a high power output of 3W and 6 powerful antennas coming along, the GPS cell phone blocker has an effective range up to 20m, depending on the signal strength in the given area. It is absolutely one of the most practical units, since it does manage to meet most of the jamming demands for various frequency bands. With selectable adjustment allowed, turning on/off any single ban will not interfere with the regular operation of other bands. Therefore, users can choose to jam specified signals at free while still allowing access to other signals.
