2.4 ghz Jammers
Well, my family member who is in corporate security enlightened me to the new art of jamming 2.4 ghz. Its actually becoming popular however I'm not sure how legal. They have installed a new 2.4 ghz and cell phone jammer in thier office. It blocks the entire 2.4 spectrum and all cell phone bands. The range is adjustable but the power seems to be quite a bit more than advertised. I guess they are becoming more popular for corporate security because they had a 3mo wait to get the unit which is about the size of a car stereo amp with a few antennas. It also controls personal cell/txt usage amongst cube rats. Wouldnt mind having one at home....When Dad says your grounded from it he means it! Fore more research just search for 2.4 ghz jammers.
Anyway for those who fly electric in and near industrial parks, look out. (it stomps out a JR pretty easy at low power way across a huge parking lot)
