The main concern is commercially available drones though, bought by idiots. Anyone who can build a drone is probably intelligent enough not to fly by airports unless their sole purpose is to do just that. If they are determined to get through airport security, they will and they will build a drone specifically designed for that.
My jammer can be used for any airport, prison, border agency, coast guard, police service etc...and as stated in the initial post, is designed against most commercially available drones.
It can also be adapted to block 3g, wifi and 2.4g using omni directional antennas. This is for public order issues. Although I don't agree with the police being able to do this, some agencies in the US - land of freedom - have expressed a interest...
Morals or money? Hmmm...
