People are more likely to use it on a peeping tom's drone. How long before people are using these drones to spy on my daughter? If the young man/woman works out that the yagi on the anti-drone device is in the high UHF or GHz range, so they use a VHF radio module, maybe bending FCC rules by using the 2m ham band, I would encourage my daughter to spend time with them.

Who are we kidding? The parents are a geeks, and she'll rebel by hanging out with cool people.
