Radar jammer is a device which is used for obstructing the signals coming out of the speed detectors of the police.These are meant for avoiding a speed ticket which is a bit tricky task.Radar jammers scramble the signals allowing the motorists to get away.These are quite compact in size whose prime function is to scramble the signals coming from radar detectors.
Initially the radar jammers were very heavy and bulky and operating them was very cumbersome task.They used to beep continuously if there were detectors in close proximity.The drawback associated with them was that by the time they used to lose their calibration which results in reducing their jamming efficiency.

The radar jammers are available in two types such as active and passive jammers.Active radar jammers are designed in a way that they should emit their own radio signals.They generate their own radar bands and jam the signals coming from radar detectors.Initially the active radar jammers were X and K band types and were very effective also.But with the invention of Ka band it became very difficult due to the bandwidths spectrum.
The active jammer works on the theory of interference the Doppler shift that produced due to reflected radar beams.These reflected beams are used by the police radar guns for obtaining the speed of the vehicle.
Passive radar jammer has acquired most of the market of radar jamming devices.Around 98 percent of the jammers used by the people are of passive type.These are designed in a way that they should reflect the signals coming from the radars of the radar gun.These reflected signals mixed with an FM chip reaches back the radar gun to make it a bit confuse.
These are most efficiently used within the 100 feet from the speed gun.
Before installing a radar jammer in your vehicle, one should check out with the laws or the models or the types that are permitted to use.The purchase of these devices is legal and only permitted models should be used.
Most of the European countries have made the use of radar detectors an illegal act while they are legal in most parts of United States.The vehicles which weigh over 10,000 pounds are not permitted to have radar detectors.Also they should not be used around the military areas.
The use of radar jammers are illegal throughout US, if a driver found guilty of using a radar jammer, he may be fined or imprisoned.
There are several radar jammers available in the market but Viper Radar Jammer will certainly pull your sight with its features.The functionality of the device makes it one of the most exceptional equipments.This is able to detect the signals of X, K and Ka band radar along with the most advanced POP radars.
It does not violet the FCC regulation as it works as a receiver and not as a transmitter.Hence they are most widely used radar jamming device.There are several other radar jammers that can be used for are Blinder M-20 or M-40 or the Lidakek LE-30 which are designed in a way that they give minimum 'error codes'.
