Handheld Digital Signal Jammer Block GPS Glonass 4G With 2.5dBi Omni Antennas

Handheld Digital Signal Jammer Block GPS Glonass 4G With 2.5dBi Omni Antennas

The signal Jammers 6.5Watt is designed to block communications between two RF Wireless equipment like Mobile phones and Cellular base station, Glonass, GPS, Wi-Fi 11 a/b/g/n, WIFI, SAT Cell phones, Radio Phones or Remote Controls without interfering with other communication systems.

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.

Handheld Signal Blocker Features:

(1) Compact Size and easy carry

(2) Multiple bands ,Individual channel on/off with selector switches

(3) Long battery life (>1.5hours)

(4) The digital signals modulated to VCO, produce RF signals, resemble noise signals in the RF spectrum, guarantee the interference efficiency between the traditional VCO and digital interference source.

(5) jamming eight RF frequencies with four antennas.

(6) UWB frequency matching technology employed to reduce the antennas quantity and enhance the working efficiency.

(7) Do not turn on device until antenna fixed.

Digital Gaussian white noise is essentially a pseudo random signal, signal characteristics consistent with a random function. Strong Anti-interference ability, there is no need high power interference radiation power, influence and damage to the electromagnetic environment is very small, can bear long distance loss. Long-term cases, interference stability. Mechanism causes due to interference, interference by external environment (such as wind, rain, ice, variations on space) change is not obvious.

There are 3 types RF Jammers.

1. VCO(voltage controlled oscillator) Technology

2. DDS (Direct Digital Synthesis)Technology

3. Pseudo random digital Gaussian white noise technology.

General speaking,

1. VCO(voltage controlled oscillator) Technology

Requirements for the jamming range is not high, extremely sensitive civilian consumption levels of low cost, but efficiencies are not very strict scene.

2. DDS (Direct Digital Synthesis)Technology

Requirements for the jammer need wideband frequency range, and choose different frequency range, such as 20-3000MHz NO gap jamming.

3. Pseudo random digital Gaussian white noise technology.

Requirements for the jamming range is very high, can accept high cost, national security and military, have strict requirements for jamming range.
