To cure this requires a very expensive isolator. First, the amplitude variation is very small compared to the signal of the car so it is difficult to get enough for a reading. ![]() Naturally, there are a few problems with this approach. If this works, the processor would effectively see the modulation and one could basically just dial in any speed they wanted. The idea behind this approach is that the mixer diode in the radar gun will see the extra energy go up and down and amplify this change in its processor. The first is a simple transmitter tuned close to the police radar frequency that is turned On/Off (modulated) at a set frequency. There are two Radar Jammer techniques that have been used for the consumer. The FCC defines a Radar Jammer as ‘…any device that contains an intentional radiator and emits radio frequency energy.’ An intentional radiator is a transmitter that generates its own radio frequency and emits it into the environment. They have been deemed to be illegal by the FCC. Radar Jammers are basically transmitters tuned to be at or close to the police radar frequency. Further, as soon as the car starts moving, centrifugal force will keep all the balls stationary instead of ‘rattling around’ randomly to confuse the radar – that cannot even see them anyway! Radar Jammer This means that when you put the metal foil between the hubcap and the steel wheel, there is no way for radar to penetrate inside to even see them. Unfortunately, most hubcaps are made of metal or, now, chrome plated plastic. This came from the World War II technology of dropping strips of metal foil from aircraft to hide from the enemy radar. ![]() For example, how can one believe that a fluorescent tube can magically absorb radar beams? While they will interfere with a radar gun and give a false reading when operating, there is no physical mechanism for anything like that when they are just laid on the dash.Īnother popular thought was putting tin foil in the hubcap. Some of the different methods to disable police radar are just silly when you think about them. We thought it would be a good idea to explain all these efforts by telling you what they are and how they work. Recently, Rocky Mountain Radar introduced radar scramblers, or ‘passive’ radar jammers. ![]() Of course, the FCC was quick to adjust the rules to keep these off the street. Some of these were just silly – remember the ‘put a fluorescent bulb across your windshield? – Oh, and put balls of aluminum foil inside your hubcaps? Others were more intentional radar jammers, electronic devices designed to interfere with the radar gun. Over the years many people have designed (or tried to) systems to help defeat the radar traps. Car radio scrambler drivers#It just doesn’t seem fair to penalize drivers for going just a little above the limit. After all, the cops just use radar to generate revenue for the cities and towns across the country. ![]() It’s long been most drivers’ dream to go past a policeman with radar and blow up his radar gun.
