“Chuyka 4.0” is a portable four-band electronic intelligence device designed for real-time detection of UAV signals. It is intended to detect analog video signals and monitor drone activity in the radio spectrum. “Chuyka 4.0” helps identify potential aerial threats in advance, providing additional time for response and decision-making.
After switching on, the “Chuyka 4.0” automatically scans the radio spectrum across four frequency bands and analyzes active signals. When activity is detected, the device provides visual and audio alerts, displays service information on the small screen, and, if a relevant signal is available, can output intercepted video to the large screen.
The “Chuyka 4.0” ELINT device operates in four frequency bands: 1080–2200 MHz; 2860–4500 MHz; 4860–6040 MHz; 6040–8800 MHz. An additional fourth module expands radio spectrum monitoring capabilities and enables broader frequency coverage compared to previous versions of the device.
The detection range depends on the operating frequency, video transmitter power, antenna type, terrain, obstacles, and other operating conditions. In the 2860–4500 MHz band, the detection range is 3 km: at frequencies up to 4000 MHz, it may be greater, while at frequencies 4000–4500 MHz, it may be lower. For the 6040–8800 MHz band, the detection range is from 3 km.
The main difference is the addition of a fourth frequency module (6040–8800 MHz) and a fourth antenna. “Chuyka 4.0” is also equipped with a video output for connecting an external monitor and an input for an additional or continuous power supply. This expands the device’s capabilities for field and stationary use.
The device analyzes analog signals within defined frequency ranges. Its primary purpose is to detect UAV activity and display service information about the recorded signals.
No. The “Chuyka 4.0” operates in fully automatic mode and requires no complex configuration. After being powered on, the device immediately starts scanning the radio spectrum and is ready for use.
No. The “Chuyka 4.0” operates in a passive mode and does not emit any signals during scanning. As a result, the device does not reveal the user’s position and remains undetectable to enemy electronic reconnaissance systems.
The video output allows connection of an external monitor or another display device to show the intercepted video signal. This feature can be useful when operating from stationary observation posts or command centers.
Yes. The device has a connector for connecting an additional battery pack or a continuous external 9 V DC power source.
The built-in battery provides up to 2 hours of operation. The additional battery pack adds up to 4 more hours, allowing the total operating time to reach up to 6 hours.
The device is used by military units, mobile groups, volunteer organizations, UAV operators, and users who require radio spectrum monitoring in high-risk areas.
The original “Chuyka 4.0” ELINT device can be purchased through the official BlueBird Tech website. For consultations regarding specifications, configuration, and purchasing terms, please contact +38 073 864 04 07 and use only official communication channels.
According to subparagraph 5 of paragraph 32, subsection 2 of Section XX of the Tax Code of Ukraine, certain defense-related goods may be supplied without VAT if their end users are law enforcement agencies, the Ministry of Defense of Ukraine, the Armed Forces of Ukraine, the National Guard of Ukraine, the Security Service of Ukraine, the State Border Guard Service of Ukraine, the National Police of Ukraine, voluntary territorial defense units, other military formations established under the laws of Ukraine, other security and defense sector entities, as well as enterprises acting as contractors or subcontractors under state defense contracts.
To apply VAT-free pricing, it is necessary to document that the products are purchased specifically for defense needs. Such confirmation is provided by an end-user certificate.
The status of a military service member, police officer, or employee of another security agency does not, by itself, grant the right to purchase goods without VAT. If the product is purchased by an individual for personal use, it is sold at the standard price including VAT, in accordance with the requirements of the Tax Code of Ukraine.
Purchasing without VAT is possible only if there is an end-user certificate confirming that the final recipients of the goods will be law enforcement agencies, the Ministry of Defense of Ukraine, the Armed Forces of Ukraine, the National Guard of Ukraine, the Security Service of Ukraine, the State Border Guard Service of Ukraine, the National Police of Ukraine, voluntary territorial defense units, or other military formations established in accordance with the laws of Ukraine.
It is also possible to conclude a contract with a legal entity, charitable foundation, or non-governmental organization, provided that an end-user certificate is supplied confirming that the products will be transferred for defense-related purposes.
In addition, a tripartite agreement may be used, where one party makes the payment (for example, a charitable foundation, non-governmental organization, individual entrepreneur, or company), the second party is the product supplier — BlueBird Tech — and the third party is the recipient, namely law enforcement agencies, the Ministry of Defense of Ukraine, the Armed Forces of Ukraine, the National Guard of Ukraine, the Security Service of Ukraine, the State Border Guard Service of Ukraine, the National Police of Ukraine, voluntary territorial defense units, or other military formations established in accordance with the laws of Ukraine.
For selecting the optimal option for processing, we recommend contacting our managers and specifying who will be making the purchase: a military unit, charitable foundation, non-governmental organization, individual entrepreneur, company, or private individual.
An end-user certificate is a document that confirms that the final recipients of the products will be law enforcement agencies, the Ministry of Defense of Ukraine, the Armed Forces of Ukraine, the National Guard of Ukraine, the Security Service of Ukraine, the State Border Guard Service of Ukraine, the National Police of Ukraine, voluntary territorial defense units, or other military formations established in accordance with the laws of Ukraine.
The presence of an end-user certificate confirms the defense purpose of the procurement and allows the application of a special VAT exemption regime in cases provided for by Ukrainian legislation.
If the end-user certificate is not available, we are required to process the sale at the standard price including VAT.
