Drones Killer: We have jammed-jammed, jammed-jammed, jammed-deaf ...
Alexey from Jammer.su approached me and said that they are developing professional jammers of the entire drones . I offered to go to visit Maxim from CopterTime and try to muffle their copters. That's what came of it.
Glushilka is harsh, even without a directional antenna, it completely muffled the kopter at 300 meters.
Of course, we had the first thought to come to a tournament or an exhibition of drones, turn on the jammer, and then distribute the business cards of the drones repair shop to everyone. But now it's not the 90s and we have white hats.
Bobuk trumpeted to the whole world, they say, saying that "the Kremlin’s GPS is not real", allegedly with the aim of jamming the kopter.

Suppressor Wi-Fi and radio frequencies in the 2.4 GHz and 5.8 GHz bands.
Today, the most common is WiFi at a frequency of 2.4 GHz. This is due to the fact that the outdated standard Wireless-B and Wirelles-G operate at these frequencies. Over time, this channel becomes More and more loaded and begin to appear loss of speed and interference.
Powerful coolers for cooling. Working temperature: from -40 to +55 degrees.
Therefore, a new technology has emerged that provides access at a frequency of 5 GHz. The transmission channel in this range has become much broader and more functional. in comparison with 3 on the 2.4 GHz frequency. A large number of spyware can also transmit information on these frequencies. This jammer was created to prevent such situations.
Under the hood
The device weighs 10 kg and is used in a stationary mode. A lot of weight is perfectly explained by the radius of work - the jammer is able to turn off WiFi transmitters in a radius of 100-600 meters.
Warranty 1 year, subject to compliance with the mode of operation.
In no case should the device be switched on without antennas.

On the one hand, this disciplines the owners of drones, who feel permissiveness, on the other hand, the number of corpses of drones at the bottom of the rivers will increase (as is the opposite of MOs in the Park of Culture).

Tips for drone owners
Maxim from CopterTime :
“Before turning on the device, I was pretty skeptical and was sure that the DJI quadcopter could not be muffled, and after turning on the device, skepticism had passed. The control signal and GPS were lost, but thanks to the smart system, the copter did not fall, but gradually decreased, the sound of the motors made it clear to everyone around or below about their intention to sit down.
Some tips for DJI Phantom 3/4, Mavic Pro and Inspire quadcopter owners:
1. Before flights, enable the Multiple flight mode in the settings.
2. If the signal is lost, try to approach the quadcopter as close as possible and switch from P to A mode and back.
3. It also helps to properly route the antennas or use amplified antennas or reflectors.
As shown by surveys among buyers of quadcopters, no one knows by whom and how the use of jammers is regulated. And many buyers express their concerns that jammers can be used without proper authority. ”
Alexey from Jammer.su :
“In my opinion, it would be wrong to say about jammers as about“ disaster ”and the infringement of rights. Because, fundamental - this is the purpose of using the device - either protection, or damage, whether it is an ordinary person or an organization.
There are already many precedents with the use of criminal drones. As an example, to carry weapons, drugs in prisons and across the state border, spying on personal life in order to collect compromising materials and blackmail, which in turn is a violation of rights.
As a result, I want to say, there will always be disgruntled people, but with proper use and reporting of the drones jammers, they will occupy a certain niche in the security of their personal life, business and the country as a whole. ”
