Single band 20W high power jammer blocker isolator shield,GSM 3G 4G Wifi GPS can be chosed

Technique characteristics
1.Block single signal on the GSM, CDMA, DCS, PCS, GPS, 3G or 4G bandwithout interrupting any other electronic device. 2.Users can turn the device on and off for instant jamming and unjamming. Also included is sensitivity control for partial and selective blocking of any mobile phone signal.
3. Control turn ON/ OFF and adjust output power by hand. Taking use of technology of interference superhigh frequency.
4.High effective channel power with rater big semidiameter of interception.
5. Effectively making subsections, just interferencing downlink and causing no interception of base station.
