Any RF engineers know how feasible it would be to take a yagi or other directional antenna and put it on a gun stock and make an RF jammer that could be directed at drones?<p>I was once testing a quadrotor that we built for IED detection with a group of marines, and we discovered that the metal detectors that the IED teams were carrying were able to completely fry our electronics from a couple of feet away. I'm guessing the power required to do this from 100s of feet away is significant, and the FCC doesn't take kindly to these sort of activities, but it doesn't seem crazy if you only need a short but intense burst.
It's struck me for some time that it's clear that drones should be fairly easy to take down, and it must be one of the difficulties that e.g. Amazon is facing in deploying delivery drones. All you need is a well-placed net.
Is this solution really any better than a simple T-shirt cannon?

Would love to see that big, heavy hex trying to catch a 250mm quad on a 6S LiPo, e.g. <a href="https://www.youtube.com/watch?v=dxU4GdlTHDg" rel="nofollow">https://www.youtube.com/watch?v=dxU4GdlTHDg</a>
Fleets of drones are the only solution. And then: Drone-making drones! And then: Drone-parts-harvesting-drones!<p>Only then can we have the drone wars we deserve.
Considering the small size of civilian drones and their mostly plastic composition, such air combat antics are entirely superfluous - light lasers will handle airspace interdiction nicely & cheaply.
It looks like the quad getting ensared is a DJI Phantom. While a net will do the job, all you really need to mess a Phantom within wifi range is a copy of SSH.
