I remember reading a long time ago some odd story, that one would be able to disable instruments at a relatively low flying airplane, by aiming at it a conventional parabolic satellite dish with a strong microwave component mounted on it. Anyone care to explain if this was just some urban myth or if there is any truth to that? Are there any other ways to "jamm" digital devices from a distance? Edit: The story seems to be too simplistic, but it there are at least certain devices around that use microwave power to jamm electronics: http://dx.doi.org/10.1109/PPC.2009.5386327 http://dx.doi.org/10.1109/PPC.2009.5386327 http://en.wikipedia.org/wiki/Bofors_HPM_Blackout http://en.wikipedia.org/wiki/Bofors_HPM_Blackout
