8 Band Digital Portable Signal Jammer Block Mobile Phone Signal 2.5dBi Omni Antennas
This portable signal jammer GW-JN8DGN design 8 channels with 4 antennas.
digital noise technology jamming range is very high, 2 times stronger than VCO technology jammer.
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.
Portable Signal Jammer Basic Features:
(1) Compact Size and easy carry
(2) Multiple bands ,Individual channel on/off selector switches
(3) Long battery life (>1.5hours)
(1) Compact Size and easy carry
(2) Multiple bands ,Individual channel on/off selector switches
(3) Long battery life (>1.5hours)
(4) Don't put the jammer into the water or fire to avoid using in the bad Condition like over-wet, over-hot, high voltage and high magnetism.
(5) jamming 8 channels with 4 antennas.
(6) with Digital Gaussian White Noise Technology.
Portable Signal Jammer Applications:
Border control units, checkpoint personnel, Meeting rooms, Hospitals,
Banks, Churches, Conference Rooms, etc
