Oh Great.... just what we need to show up at the flying field!
I saw this article on the following web site:

Long-Distance Jammer Is Taking Down Drones[/h] 10/21/2015
The battle for control of the skies continues. As the amount of unmanned aerial vehicles (UAVs) increases each year, contracting parties are stepping up their efforts to keep the devices out of the air. Battelle, a large nonprofit research and development organization headquartered in Ohio, has now developed a portable, shoulder-mounted rifle, dubbed the DroneDefender, that attacks UAVs with radio waves.
In a press release from Battelle, the gun is stated to use “radio control frequency disruption technologies to safely stop drones in the air, before they can pose a threat to military or civilian safety.” A video accompanying the post describes that it operates on standard GPS and ISM radio bands, allowing for it to interference with commercial UAV signals.
Reportedly, the DroneDefender can hit objects up to 400 meters with an effective cone diameter of 30°. This is about as far as Battelle goes with the technical details, so the actual frequency ranges of the rifle still remain unknown. However, it is easy to determine which ISM radio bands they most likely run on by looking at the consumer UAV market.
The DJI Phantom series, for example, as seen in video above, shows that the DroneDefender is likely targeting the 2.4 GHz range (if it is attacking the Phantom 1 or Phantom 2). This puts them on the same range as standard Wi-Fi networks, Bluetooth connections, microwave ovens, car alarms, baby monitors, and ZigBee devices. To disrupt the GPS signal, the rifle needs to broadcast at 1575.42 MHz or 1227.60 MHz, depending on the UAV.
When a remote control signal is interfered with, drones will often enter into their safety protocols, which usually includes one of three options. It will either hover in place until the pilot can regain a control link, attempt to land so the pilot can recover it physically, or try to return to its point of origin. Since the DroneDefender is mentioned to be attacking the GPS signal as well, the likely scenario is that the device will hover for a while or try to land.

At only 400 meters that is well within visual distance of anyone using one of these probably and I would say this is of little concern since it is most likely very expensive. Probably being developed for military applications and the link posted to the article also makes it sound like it is most likely illegal to use one of these.

I remember reading an article years ago about a revolutionary automotive engine that got insane fuel economy as well as great horsepower output. The article said it used microwave technology for the ignition system and that if you touched one of the ignition leads while it was running......... it would kill you.
It didn't go into production for some reason.
