Today, advanced police radar guns can indicate to police officers that someone is attempting to interfere with them. They easily achieve this by monitoring the return frequency of the jammer during periods when the gun is not firing - this is a dead end for active jammer users.

Can the police detect the radar signal jammer?

This is because the interference caused by the radar jammer to the radar gun is very obvious. The police will know if they are using radar jammers, even if they are actually unable to track your exact speed.

Is the radar jammer used legally?

Unlike most states that can legally interfere with police lasers using laser jammers, police radars cannot legally interfere anywhere. In fact, any attempt to do so (whether successful or not, most active radar jammers are unsuccessful) is a federal crime and violates FCC regulations.

Older analog radar jammers do have certain radar jamming effects on older analog X-band and K band radars, but they are usually bulky, cumbersome to operate, and operate continuously - each radar detector is set nearby. Their use will ultimately have a negative impact on the driver in front of you, who will brake and slow down, which poses a potential safety issue for drivers using radar jammers.

In some cases, the jammer may unintentionally generate higher indicated speeds on the officer's radar gun! Can you imagine trying to explain to the police how his 95mph reading was introduced by your jammer instead of your actual speed?

What about radar cell phone jammer?

• Although radar detectors can be legally owned and privately used in California, radar jammers are completely prohibited. This position has been responded to by several other state and federal laws.


• 
  Radar jammers not only severely interfere with police radar systems, but also with radar systems used on aircraft. This is one of the main reasons why the use of radar jammers is considered illegal under the California Radar Detectors Act.


• 
  If you are using a radar gps jammer, the police can easily detect it. This is because the interference caused by the radar jammer to the radar gun is very obvious. The police will know if they are using radar jammers, even if they are actually unable to track your exact speed.


• 
  Although it can penetrate most common types of building walls, ceilings, or floors - including poured concrete, concrete blocks, bricks, wood, plaster glass, adobe, and soil - it cannot penetrate metal.
