8 Band Portable Jammer with 3 Times Jamming Range than VCO Technology Jammer

8 Band Portable Jammer with 3 Times Jamming Range than VCO Technology Jammer

This jammer GW-JN8DGN design 8 signal frequencies with 4 antennas.total 6.5W.

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.

Portable 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) 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.

.

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.
