British soldiers tune radio waves to fry drone swarms (www.gov.uk)

UK-made, invisible radio wave weapon knocks out drone swarms for the first time.

Weapon has potential to help protect against drone threats as nature of warfare changes.

It sounds like it's a directed microwave cooker. Works on people too, just not ones behind good cover.

Edit: ah, high frequency, my bad, it's a gamma gun. Same principles apply I think, give or take the cover.

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). Furthermore, I don't think we have a way to produce gamma rays in any high intensity in the lab. matter-antimatter annihilation and fusion bombs are the only way I know of for humans to produce gamma rays. The former can only be done at atomic scale in the lab and the latter is, well, I guess that also destroys drones (and everything else within 100km)

High frequency radio is still below the visible part of the spectrum, gamma is waaay above it.

Tech Ingredients YT channel made a diy microwave directed energy device to disrupt consumer drones.
