VHF UHF Mobile Phone Signal Jammer High Power for Walkie Talkie ,
50 - 300m Shielding Range
Signal Jammer Introduction:
RC-IEDs (Radio Controlled Improvised Explosive Devices) and IEDs
(Improvised Explosive Devices) are the weapon of choice used by
terrorists in conflict zones. Home made IEDs and roadside bombs are
remotely activated by transmitting an RF signal, via a remote
transmitter, to a receiver attached to the bomb or improvised
explosive device.
Now let us introduce this mobile signal jammer to you ,and make you
better understand about the positions of all the buttons, function
of accessories and other hardware.
The VHF and UHF are low frequencies (130-180MHz,400-450MHz).They
are used for many devices in our life.For example,the security
walkie-talkies, mainly held by the police and security personnel,
use these frequencies to work.What's more,if you live in the big
city, you can see many monitors,or CCTV cameras in the
buildings,streets which all work with the UHF/VHF frequencies.And
some monitors may be decorated in the hiden places that you didn't
know they are spying on you,which violate your privacy right.The
UHF/VHF jammer can interfere the signals so that the spy camera
cannot see you anymore.
Signal Jammer Technique characteristics
1. Taking use of super-high frequency with high
effective power amplifier.
2. Effective output power (channel power) to ensure
big interfere radius.
3. Only interfere downlink frequency of mobile
system,without disturb normally working of Base Stations.
4. Imported elements: Slow start up design of circuit.
These elements can maintain the stable operation condition with
high integration.
Interface
1. Three N interfaces, Which are using to connect
antenna
2. One power supply interface for AC220V input
System fittings
Jammer machine,power line,RF cables and antennas etc.
The 3 channels are responsible respectively for 3 different
frequencies.
Antenna
Omni Antennas
Frequency:130~180MHz, 400-450MHz, 450-500MHz
Gain: 7dBi
Interface: N
RF Cables
3pcs 5-meter 1/2 super soft cable.
Notices
1. Be sure to connect all the antenna before the
power supply is switch on. Please do not take off antenna when the
machine is working.
2. Antenna shall be used vertical to the ground,
working more efficiently.
3. Please don’t put the jammer in the water and fire
to avoid using in the bad
condition of over-wet, over-hot, high voltage and high magnetism.
4. If the jammer can not be charged or other
unconventionality( the indicator light doesn’t light up), please
contact with the distributor in local place. Any refit and
incorrect repair is not allowed.
5. Any ruin and disrepair caused by incorrect
operation and disassembly will be excluded from the repair with
free of charge.
