In recent years, the market of UAV has been growing rapidly. With
the large-scale R & D and production of factories, such as
Xinjiang, extreme flying, zero degree intelligence control and so
on, the commercial UAV is very cost-effective and has become more
and more popular. However, domestic supervision of UAVs, especially
the "black fly" UAV, is still in a blank state. The proportion of
the UAV flying in the air is about 90%, which poses a great danger
to air surveillance and air safety.
JQ communication, as an excellent security equipment supplier,
independently developed the UAV jammer, the device can interfere
with all GNSS satellite positioning signals, including: GPS/ Beidou
/ Gore / Galileo, and can also interfere with the common ISM 2.4G
and ISM 5.8G frequency bands of unmanned aerial vehicles, forcing
unmanned aerial vehicles to be remote. Control, map location,
signal interruption to achieve the purpose of landing / returning /
JQ Communications independently developed UAV jammers, with strong
functions and far distance interference, up to 1-5 km.
Shenzhen ninth district science and Technology Co., Ltd. has
interfered and shielded the GPS satellite positioning signal, and
can also interfere and shield the 2.4G and 5.8G frequency bands
commonly used in UAV, forcing the unmanned aerial vehicle (UAV)
remote control, map location and signal interruption to reach the
effect of the uncontrolled landing / hover / hover.

Three. Product description
The interceptor uses 4 types of portable rifle base station, which
mainly controls the unmanned aerial vehicle or flight mode under
the flight state, cut off the connection between the unmanned
aerial vehicle and the remote control. The interceptor can force
the unmanned aerial vehicle to be forced to fall or return to the
air by the interceptor, so as to ensure the low space airspace
safety in the area.
Four, installation and use instructions
4.1 installation steps and methods
4.1.1 remove the shield machine from the box.
4.1.2 turns the antenna into its respective antenna pedestal,
otherwise it will not be effective.
4.1.3 hangs the shield to the wall or the corresponding location,
the best installation height is 1-2 meters.
4.1.4 first make sure that the shield machine is full of
electricity, then turn on the power switch. The power indicator on
the power supply indicates that it is starting to work.
4.2 matters of attention
4.2.1 must first install the antenna according to the corresponding
identification on the host, and then connect the main power supply.
The effective coverage of the 4.2.2 shield is a circular area with
the center of the shield, so it is careful to choose the placement
position of the shield in order to avoid the shielding dead angle.
The 4.2.3 shield should be placed in a well ventilated place,
avoiding the shielding of large objects and avoiding the strong
electric and magnetic sources of the strong heat source, so as to
ensure the shielding effectiveness and long stable work.
4.2.4 shields should not stack other items and dismantle the
antenna when they work, so as not to affect the shielding effect
and damage the machine.
When the 4.2.5 shield is not in use, it should cut off the power in
time, so as not to affect the normal use of the mobile phone.
4.2.7 should pay attention to waterproofing when using shields
4.2.7 when the area of the site is larger than the effective
shielding range, it is recommended to adopt multiple shielding
honeycomb installations to ensure shielding effectiveness.
4.2.8 as the power supply and antenna are dedicated to the host,
and debug in the factory is a one-to-one debugging, please try not
to exchange the use, in order to ensure the best effect.
4.2.9 please keep away from corrosive gases and liquids and do well
in dust prevention and moisture prevention, so as not to accelerate
the aging of internal components of equipment.
When placing 4.2.10 outside or in the wild, we should pay attention
to adding protection devices to rats and ants.
Five. Maintenance and maintenance
5.1 the shield is a maintenance free device without maintenance.
5.2 when surface cleaning is done, chemical solvents should be
banned and water inflow should be avoided.
5.3 shields should be stored in dry and ventilated places when they
are useful, so as to avoid prolonged exposure to salt spray and
5.4 shields warranty period of one year, life-long maintenance.
Six. The answer to the problem
6.1 when the signal jammers work, why do some cell phone signals
still indicate signals?
Answer: This is just an illusion. In fact, the mobile phone is
already unable to communicate. When you press the pull button at
random, you will find that there is no signal indication on the
6.2 will the signal shield interfere with the normal operation of
other electronic devices?
Answer: No, no. This is because the electromagnetic signals emitted
by the signal shields fall completely within the mobile working
frequency band stipulated by the state, which only blocks the
communication of mobile phones. This signal is always in a
relatively static state, and will not affect any electronic device.
6.3 is the signal shielding device harmful to human body and cell
Answer: please rest assured that the electromagnetic signal emitted
by the signal shield is weak, and the test data show that the
intensity of the signal is far from harm to the human body. At the
same time, the signal shield is only blocking the forward signal of
the mobile phone, so that the cell phone can not contact the base
station, so it will not cause any damage to the phone itself.
6.4 is there any difference in the distance between the signal
shields when used indoors and outdoors?
Answer: Yes. The effective distance of the signal shield (30-40
meters) generally refers to the indoor distance. In outdoor open
areas, the effective distance of shielding can reach several
hundred meters. It should be pointed out that, whether in indoor or
outdoor use, the effective distance of the shield is related to the
environment conditions at that time, such as the distance from the
base station, the location of the place and so on. Therefore, when
using the signal shield, we should give full consideration to this
factor and avoid shielding dead angle, thus affecting the shielding
6.5 does the signal shield have the same effect on GSM phones and
Answer: this question is a good question. Because the
anti-interference performance of the CDMA mobile phone is far
superior to the GSM mobile phone, the effective shielding distance
of the signal shield for the CDMA cell phone is less than that of
the GSM cell phone, but the difference is not very large, about 2-4
meters. But it also asks the user to pay attention to some
particularly important places, and should increase the number of
field signal shields when necessary in order to ensure the
shielding effectiveness of the CDMA mobile phone.
6.6 when the signal shield is working for a period of time, the
shell is hot. Will it damage the machine for a long time?
Answer: Thank you for your careful, this is a normal phenomenon. In
design, we use the thermal conductivity of aluminum alloy wire
drawing shell to assist heat dissipation. It can guarantee long
time stable work. As a result, the machine will not be damaged by
the heat of the shell.
