250W Indoor And Outdoor Waterproof 5 Channels GPS, 2G, 3G, 4G, WIFI
Prison Cell Signal jammer
For the very important places as the prisons, the military and the
some special government agencies protect the information from
giving out is really important. In this condition blocking the
signals of the mobile phones is really necessary and if you need
one to used in such condition to cut the mobile signals this 250W
High Power Cell Phone Signal Jammer here is really a good
The first advantage of this prison cell phone signal jammer is that
it can block the 5 frequency bands CDMA GSM DCS GPS WIFI at the
same time once turn on it. And the second advantage is that since
owning 250W high output the jamming radius is of course powerful,
the jamming radius of this 250W high power jammer is up to 600
meters according to the signal strength in the detailed place. In
this case for the places where need to cut off the cell signals and
owns a big area this mobile phone jammer is suitable and plays an
important role in such condition. Thus as owning good design and
cooling system, this 60W high power jammer supports continuously
Especially for prisons and other large sensitive locations such as
military or governmental compounds. It can also use in Oil and Gas
Storage Facilities and fields, Security Services, Military Units,
Secret Services, Museums, Factory, Border Patrol and Drug
Enforcement, Customs, etc. - Remote PC control with software to
Turn each jammer, each band or the whole jammer system ON/OFF. Each
unit offers a key lock support & mounting hardware
Moreover this high power jammer is environmentaly friendly and it
will cause no harm to people’s health when you use it. Just by
using it the 3G signals can be blocked without any difficulty.

of accessories and other hardware.
with directional panel antenna,(4G/GSM/3G/WIFI)
Power supply interface (AC220V IN)
Switch on your jammer
Note: Switching on is not allowed before the all antenna have been
linked, otherwise the equipment is easy to be damaged.)
◎install all antenna at first.
◎install all antenna at first.
Input the 220V AC power, Turn on the “RED Switch”.
Press the on/off green button.
Turn off your jammer
Turn off the “RED Switch”.
Move away 220V AC power from the main machine .
The jammer is out of work.

Question and answers
1. The shell of jammer will become hot after working for some
times. Does the long working time will damage the machine itself?
It is very normal. When designing, we are thinking of taking use of
the conductivity of metal shell to help the heat sinking during our
designation. By this way, the machine can be kept in good working
condition for long time.
2. Is the jammer has the same effect to GSM cell phone and CDMA cell
The capacity of anti-interference of CDMA is much better than GSM
cell phone. So the interference effect for GSM cell phone is better
than CDMA cell phone.
3. Is there any difference of distance between using jammer indoor and
Yes. Generally speaking, outdoor signal is bigger than the indoor
signal. Thereby, the shielding effect is worse outdoor. Strictly
speaking, whether using indoor or outdoor, the effective distance
of interference is related to the surrounding around, for example
the distance between different base stations, positions of
4. Does jammer interfere the other electronic equipment to work in normal
No. Because the electromagnetic signal sent by jammer are totally
used in the band that regulated by government and just have
interception effect to cell phone communication.
5. Is jammer harmful to the human body and cell phone?
Please do not need to worry about it. The intensity of
electromagnetic signal sent by jammer is in compliance with the
national standard of environmental electromagnetic wave health. The
signal sent by jammer is relatively small and unharmful to human
body according to the testing result. Meanwhile, this device just
damage the receiving condition to the cell phone and makes the
normal connection between cell phone and base station impossible.
Therefore, no damage will occur on cell phone itself.

and other sensitive locations where the mobile phone signals are
