Comment on British soldiers tune radio waves to fry drone swarms for pennies

It uses high frequency radio waves to disrupt or damage critical electronic components inside drones, causing them to crash or malfunction.
At a range of 1km…
That‘s useful not just for drones. I wonder if this works against helicopters, too.
More like: That could be useful, just not for (perhaps many) drones.
1km isn’t that far - the drones that were used for surveillance of Minneapolis protests in 2020 were around 6km up.
If they needed to get close for some reason, would a 1km deterrent be countered enough by approaching from directly above and using gravity for the last km?
The drones used in Ukraine are basically just commercial drones with grenades strapped to them. And a 1 km distance they’re unlikely to be able to damage a target even if they detonated.
It sounds like it’s a directed microwave cooker. Works on people too, just not ones behind good cover.
Tech Ingredients YT channel made a diy microwave directed energy device to disrupt consumer drones.
High frequency radio is still below the visible part of the spectrum, gamma is waaay above it.
They are definitely not blasting gamma rays to bring down drones lol. “radio” is a specific range of frequencies so “high frequency radio” is just frequencies at the higher end of that specific range.
Gamma rays are insanely dangerous. I’m too lazy to do calculations/research to back this up but I suspect that gamma rays intense enough to reliably drop a drone would also give cancer/radiation poisoning to anyone remotely downrange (and also the operators).

Seriously this! People don’t understand that even hobby drones at a certain price point have robust rf shielding.
