How so? There are 120,000 miles of transmission lines in the USA. Not all of that is overhead high voltage, but the system is still vast. Where do you put the net?

The problem has three prongs: Detection: there is so much line, and much of it is away from regular eyes. Intermittent-moving threat: Imagine you get a report about a drone perching on your wires. You schedule and dispatch a team to deal with it. Most likely by the time they arrive on site the drone is gone. They are playing a catchup game with moving threats. Action: okay, you got a drone in sight. Either because it didn’t move away, or because you got lucky. What do you do? Mind you the lines are really high and poking things near them can be hazardous if not done correctly. So it is not just any Harry and Dick who can deal with the drone, you need someone trained and with the right equipment.
