Every few months, Ukrainian-language YouTube and TikTok see a revival of the genre: “build your own portable electronic warfare system at home in 15 minutes.” A microwave oven, an old Wi-Fi router, a T2 antenna — and according to the video’s author, you’re now the proud owner of your very own electronic warfare complex. It looks inspiring. But… it doesn’t work. Here’s why — and along the way, we’ll explain what real EW actually is.
Spoiler: your soup is safe, you are not
The most popular version of the life hack involves a disassembled microwave oven used as a “jammer.” The appeal is obvious: a device you use every day to heat lunch suddenly becomes a means of electronic countermeasures.
Three factors stand in the way, however.
- Power. A household microwave generates powerful microwave radiation, but its magnetron, waveguide, and metal chamber are designed to transfer energy inside the oven — not to form a controlled, directed beam over a distance. Converting a microwave source into an effective radio-suppression system requires appropriate antennas, impedance matching, directionality, frequency control, and other components.
- Frequency range. Household ovens operate at a fixed frequency of approximately 2.45 GHz — the same band used by some Wi-Fi and Bluetooth devices. Nobody has ever suppressed a Shahed drone with a router antenna.
- Health. Microwave radiation during normal oven operation is not harmful and does not “damage” food. But attempting to remove the protective casing and use the magnetron for unintended purposes is a direct path to burns, electric shock, or eye injury from open radiation.
A router, a receiver, an old Nokia
The same set of arguments applies to the other “ingredients” of a homemade EW system:
- Radio receivers — they receive signals but lack a transmitter with the power needed to “drown out” anything.
- Wi-Fi routers — these devices serve an entirely different purpose and operate at entirely different radiation levels. Their power output, antennas, and software are designed to provide connectivity on a local network, not to generate controlled interference against external systems.
- Old mobile phones — they have a specialized radio path and cannot be turned into a broadband jamming transmitter by simply reflashing the firmware.
- Television antennas — they receive signals beautifully, but on their own, without a transmitter, they emit nothing.
All of these are designed to receive, not to jam the airwaves. Turning a receiver into a jammer is like trying to convert an umbrella into an anti-aircraft gun because both have something long and metallic.
The law is no joke either
Deliberately creating radio interference may violate legislation on electronic communications and the radio-frequency spectrum (in particular, Article 126 of the Law of Ukraine “On Electronic Communications” dated 16.12.2020 No. 1089-IX), and in certain cases may also carry criminal-law consequences. Experimenting with powerful transmitters and jamming third-party signals without the appropriate authorization is therefore a very bad idea.
What EW is and why comparing it to a microwave oven doesn’t hold up
To appreciate the scale of the gulf between a “life hack” and reality, it is enough to look at what the Ukrainian army faces every day.
Russia entered the war with five separate EW brigades within its armed forces — a formation at that level, as Center for Defense Strategies expert Viktor Kevlyuk notes, is possessed only by Russia and China’s military.
A telling example is the Volna Kupol Garant complex, which the Russians developed specifically to suppress the Starlink signal. According to analysts at the Center for Countering Disinformation, it consists of 6 trailers equipped with Ku-band antennas providing 40 dB of gain, a 14 kW generator, and a total radiated power of up to 10–15 kW — operating on the 14–14.5 GHz channels. In other words, nowhere near the frequency range a microwave oven uses. The price of a single such complex is around $1.5 million. And that covers jamming only one specific type of satellite communication.
The most ironic part is that even this million-dollar “shield” cannot withstand contact with reality: the moment the complex is switched on, Ukrainian electronic intelligence immediately detects the heat and microwave energy signature and exposes the position. According to open-source data, this is at least the third system of this type to have been struck. The first was destroyed on 15 June by the 422nd Separate Unmanned Systems Regiment together with the SBU; the second was struck on 24 June in occupied Kerch. On 7 August, satellite imagery recorded the destruction of yet another complex at military unit No. 2156 in Gelendzhik, Krasnodar Krai, Russia.
In other words, even an adversary with dedicated brigades, factories, and research institutes cannot reliably protect a system worth millions of dollars. And yet someone still believes a disassembled kitchen microwave will do the job.
What to do if you’re drawn to electronic warfare?
It is entirely possible to explore EW legally and safely — it just takes longer than a 40-second video:
- study the fundamentals of radio physics, antenna theory, and radio wave propagation — this is an open and well-systematized science;
- follow publicly available materials on the work of specialist units and manufacturers;
- pursue a relevant education and consider formal employment or cooperation with licensed EW equipment manufacturers.
Building an effective EW system on a kitchen table is impossible, because between consumer appliances and an industrial complex lies an unbridgeable gap in power, frequencies, and engineering. And as it turns out, even multimillion-dollar professional systems sometimes sink in that gap.
