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?

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

5 seconds of searching would have saved you from looking like a dick.


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