Ukrainian "trenches" will be able to protect the Armed Forces soldiers in the trenches on the front line: what is known

In general, everything is quite simple: the obstacle unit is attached to the radiator to the paste or glue, adjusted with a dielectric screwdriver, and then connected to the SMA type antenna and power system with wires. All details will cost about $ 1000- $ 1500, depending on the configuration. "The task of the ERB developer is more" mechanical ": to arrange blocks, to put modules on radiators, to make a blow, to connect the battery and the converters," - said Sergei Flesh.

He also told in detail about each stage. The most important part of the homemade system of EWS, and here it is necessary to pay attention to whether the real power coincides with the declared - it affects the quality of UAV suppression. For example, the latest drones of DJI have a high density of pseudo -falling operating frequency (PPRC), so cheap obstacle blocks may not work against them.

You should always add the opportunity to disable GPS suppression so that you do not accidentally knock down allied drones. There are several ranges of frequencies at which UAV operates, and to supply each of them requires a separate block and antenna. Sergei Flash called the base ranges that must be "stuffing" on the front line: 1. 5 GHz (navigation); 2. 4GHz (management); and 5. 8 GHz (management). There is also a range of 5. 1 GHz, which are rarely used.

There are options for blocks from 5 watts to 100 watts, and the higher the power, the more difficult it is to heal from the battery, and the device is heated faster. Antirone guns are usually used by 10 watts and operate on radiators, but options from 20 watts and above require a fan. All blocks are designed for 28 V. The expert warned that it is not necessary to connect 24 V, since in this case the power will fall by about 20%, and with it the efficiency of drones suppression.

The design of the complex depends largely on whether it will be powered only on the battery or even on the socket on 220 V. Options for the solution of the problem three: take the battery at 28 V; use DC converters; Use a power supply with a 220 V converting 28 V. "I personally like to tie up to 12 volts so you can connect RB banal to any car battery or car. So I would use converters 12-28 Volts. The power source is 220 at once 28 or 220 by 12 volts, ”Sergei said.

To operation of the device in the mode of the rifle requires directed antennas, and in the mode of "dome" - circular. In the case of directed, you can make wave channels or logoperiodic antennas by connecting them directly to the board. This option works well with blocks of 10-20 watts, it is only important to store a distance of at least 8 cm between the planes of the antennas. External antennas from WiFi radios with a range of 2. 4 and 5. 8 GHz will also be suitable.

For the "dome" you need to get vertical collinear pins, which have a good fastening factor in a circular plane with a failure exactly into the zenith (up), which does not particularly interfere with closing the sky, since the drones always fly on the side. The specialist also recommends using clover antennas. Cable adapters will need to be made from the module connector to the antenna. The cable can be used for RG316, RG178.
