8 Frequency Band Handheld Jammer Mobile Phone Signal Blocker 30m Range
The hand-held jammer has 8 signal frequencies and 4 output port , with 1 antennas to each port, arranged in turn of frequency level. Each signal frequency independently controlled via separate dial switches. 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.
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.
Signal Blocker Technology Brief Introduction:
1. Based on simulation of VCO interference source.
2: The digital signals, modulated to VCO, produce radio-frequency signals, resembling noise signals, in the radio-frequency spectrum, guaranteeing the interference efficiency between the traditional VCO and the digital interference source.
3: UWB frequency matching technology employed to reduce the antennas quantity and enhance the working efficiency.
Signal Blocker Applications:
Border control units, checkpoint personnel, Meeting rooms, Hospitals,
Banks, Churches, Conference Rooms, etc
