"fits on a truck"

I think thats the problem though. Nearly all of the nightmarirsh drone footage attacks in Ukraine is dismounted soldiers. Seems like the best defense would be shotguns and some sort of electronic fire control if you wanted to get really fancy.

thephyber•9mo ago
Layered defense. AND is better than XOR in this case.

The Ukrainian soldiers with shotguns can be overrun by an swarm and a shotgun’s effective distance isn’t great compared to how high drones fly for scouting. Better to have a truck mounted heavy weapon behind you and shotguns covering grunts on the front line working together.

That said, the front line of the RU/UA war is not the only useful place for this weapon. Presidential rallies, augmentation of the Iron Dome, defense of civilian airports, etc are all good candidates for a large truck-mounted weapon to counter swarms of drones.

great points
weard_beard•9mo ago
So next week RF shielding that costs a fraction of what it costs to produce this truck mounted weapon gets added to drones and we find a new optimal TWR?
impossiblefork•9mo ago
Yes, but presumably at some cost to drone's performance.

I wonder how feasible it is to build something like this for back yard scale? I just want to fry the drones my neighbor flies crossing my yard. Is there some kind of distance squared dynamic going on? That would imply I could run a small device off a car battery right?

Netting spread across tall poles are about the only thing that is not outright illegal. HOA's and some towns will throw a fit about the netting. Using radio weapons outside of a war-zone will likely result in fines if it interferes with anything revenue generating and possibly even arrest.
