Check Popular Mechanics and the other magazines like that. I've seen them advertised in some of the pubs. That being said, any device that radiates is illegal without a license (which you cannot get) so you will go from the frying pan into the fire if caught with a jammer ![]() A number of years ago I designed and built a corner reflector system that was rotated by the wind stream as the car drove along. It rotated at a speed based on wind stream and the theory was that it would reflect the radar signal back to gun and show an off scale reading. I also tried a slower speed so the returned signal would show a lower speed than vehicle actual. Since the signal being reflected was the same principal as the return from the vehicle (no active radiator) it would be legal. Bottom line, I found that if I made the corner reflectors a reasonable size, then they did not reflect a larger signal than the automobile. They would have had to been so large to work they would have been impracticable to mount on the automobile (front bumper, etc.) My device was wind driven and had a rather slow rotational speed. Maybe one of these days will modify and drive the system with a 12V DC motor and gearing to get a rotational speed of 5K-10K so effective area will exceed the return from the automobile reflective area. Interesting project and may one of these days do some further work on other legal methods of blocking/modifying radar gun signals. G Have also been making some napkin drawings of using the Luneberg Lens principles. Also a method of shifting the radar return frequency (passively) to give legal speed readings (or a zero reading on officers gun). Now what does this have to do with flying. System could be placed on aircraft to change (augment, eliminate or modify) return.of pulse type radar.

My LED readout then showed JAMMED. I had to laugh as I could just see him shooting me the bird as he flew by.
