Technique characteristics
- Taking use of super-high frequency with high effective power.
- Effective output power (channel power) and bigger interfere radius.
- Only interfere downlink frequency of mobile system,without disturb
normally working of Base Stations.
- Imported elements: Slow start up design of circuit. These elements
can maintain the stable operation condition with high integration.
A combination of the Israeli and United states of American
Technology. Most sensitive Components imported from Germany,
Hungary and Japan.
Connect:
- Four N interfaces, Which are using to connect antenna

Start Use:
- Open the package -
Carefully open the package, keep all package boxes for later
shipment.
Check whether any fitting is good or not, if any damage happened,
please contact your provider immediately.
- Connect system fittings -
Connecting the system fittings, connector lines are used to link
the main package equipment with antenna by comparison of the top
view. (The antenna must be firstly installed on solid poles)
After connecting the system fittings, a power line is used to
electrical outlet at the other end and the other end is put into
power socket.(switching on is not allowed before the all antenna
have been linked, otherwise the equipment is easy to be damaged.)
WARNING: JAMMER MUST NOT BE CONNECTED TO ELECTRICITY UNLESS ALL
ANTENNAS ARE INSTALLED
Switch on your jammer:
- After all lines (including bother connector lines and power
line)have been linked.
- Connect 220V power at the back of main machine
- Turn on the red switcher “on” position
- The output power of jammer is maximal in this situation
- Adjust the small switchers to control output power according to
requirement
Switch off your jammer:
- Turn off the red switcher on “off” position
- Move away 220V power at the back of main machine
- Move away panel antenna.
- The jarmmer is out of work.
Jamming functions:
According as theoretic
Wireless communication is effectively completed by ensuring
adequacy carrier signal density to a certain noise density during
communication. A same frequency distortion signal is used to
increase the ratio of carrier signal and noise (Nf) for shutting
off the communication between the base station and mobile phone.
The output power of jammer is given, the shield radius in the
situation of free space is confirmed according to the receiving
signal lever from base station and free space attenuation in pass
through. The below is given as a formula of confirming shielding
radius and a table of comparison of distance and pass through,
based on carrier receiving power from base station, output power of
jammer as well as gain of antenna.
Pch+Gat-L+FAF≥Prx
In the formula:
| Pch : | Minimum of carrier output power of jammer |
| Gat : | Gain of antenna |
| L : | Attenuation in pass through |
| FAF : | Amending Figure of pass through, choosing 6db for 1.8G |
| Prx : | Maximum of carrier output power of base station |
Compare distance with attenuation:

Typically testing records:
Principle block diagram:
Choosing installation position:
1.Use all omni-directional antenna (in common sense, it is not
approve of using) the transmit antenna should be put in the middle
of shielding area as below shown.
2.Use directional antenna, the transmission antenna should be put
at the edges of shielding area as below shown.
Notice:
- 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.
- Antenna shall be used vertical to the ground, working more
efficiently.
- 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.
- 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.
- Any ruin and disrepair caused by incorrect operation and
disassembly will be excluded from the repair with free of charge.
Question and answer:
1. Does jammer interfere the other electronic equipment to work in
normal condition
-No. Because the electromagnetic signal sent by jammer are totally
used in the band width and this is regulated by government and just
have interception effect to cell phone communication.
2. 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.
3. Is there any difference of distance between using jammer indoor
and outdoor?
- 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
installation etc.
4. Is the jammer has the same effect to GSM cell phone and CDMA
cell phone?
- 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.
5. 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 thought of makin use of
the conductivity of metal shell to help the heat sinking during our
designing of the Jammer. This way, the machine can be kept in good
working condition for long time.
