High Powerful Digital Mobile Phone Signal Jammer For Classrooms Hospitals

4 Antennas High Powerful Digital Signal Jammer Block Mobile Phone Signal

Jammers are used in many different scenarios and to find the best fit for your needs, we care a whole spectrum of jammers for every possible application. However, there are so many different wireless technologies that are in use today, that we can help you to accomplish your goal with the best combinations of bands to suite your needs.

This jammer GW-JN8DGN design 8 signal frequencies with 4 antennas.Each signal frequency was controlled by DIP switch independently.Digital noise technology jamming range is very high, 2 times jamming range than VCO technology jammer.

Signal Jammer Specification of Antennas with Frequency Range:
Antennal 1 channel: 791~821MHz&925~960MHz
Antennal 2 channel: GPSL2&GPSL1
Antennal 3 channel: 1805~1880MHz&2110~2170MHz
Antennal 4 channel: 2400~2485MHz&2620~2690MHz

Signal Jammer Features:
(1) Compact Size and easy carry
(2) Multiple bands ,Individual channel on/off with selector switches
(3) Long battery life (>1.5hours)
(4) Can be charged by DC 12-24V and AC 100 -240V.
(5) Jamming eight RF frequencies with four antennas.
(6).Recharging Time of Battery is just 3 hours with 12V/2A adapter;
(7) Good cooling fans guarantee effective heat dissipation
(8) The digital signals modulated to VCO, produce RF signals, resemble noise signals in the RF spectrum, and guarantee the interference efficiency between the traditional VCO and digital interference source.
(9) UWB frequency matching technology employed to reduce the antennas quantity and enhance the working efficiency
(10) Do not turn on device until antenna fixed.

Signal Jammer Applications:
Border control units, checkpoint personnel, Meeting rooms, Hospitals,
Banks, Churches, Conference Rooms, etc
