Detailed Product Description

SK-04E phone jammer is the most popular information security instrument currently. It sends out radio waves with

the same frequency bands which the cell phones use. Phone jammer causes enough interference with the

communication between cell phone and towers to render the phones unusable. The phone jammer can work by

either disrupting phone to tower frequencies or tower to phone frequencies. SK-04E phone jammer blocks all

bands from 800MHz to 2400MHz (Such as GSM, CDMA, DCS, PHS, 3G) within around 20 meters, as well as users

can adjust the jamming strength depending on different demands. The phone jammer is now a necessity for law

enforcement and the military to interrupt communications by criminals and terrorists, and also for accomplishing a

more cultured society.
