Singal-jammers are relatively common. You can buy really good multi channel jammers online. Cellphone/WIFI jammers go from $100 - $1000. Criminals use them all the time. People have so many wireless security cameras and everyone has mobile phones that jammers are becoming must have. I guess only thing that made this noteworthy was that the jammer was stationary, used continuously and was easy to find.
