OP explicitly said: “Even a horn has diffraction sidebands, and unless they're all at least 8dB down in all situations that's bad. The laser trips won't cover this.” I don’t really understand this. My guess is that they’re saying that besides the targeted microwave band, other high/low frequencies will be emitted (sidebands) and that these will diffract and be way outside of the directional beam that’s protected by the laser trip wire. I would assume the inventors have at least some explanation for this, but a fluffy article won’t go into those details.

Maybe OP meant side-lobes? https://en.wikipedia.org/wiki/Side_lobe https://en.wikipedia.org/wiki/Side_lobe

A horn? Like a fucking rhino? Glad OP covered that use case, I was concerned.

    Doesn't seem like all of his life up to this point worked, would 5 seconds make all the difference?

As you rightly noted, an article wont go into those details :). you are rising a valid point which we have addressed. Happy to explain if you PM me
