Next lets examine the different types of Radar Jammers, Passive and Active.

Passive Radar Jammers

98% percent of the radar jammers sold today are passive and are designed to reflect the incoming signal of a police radar gun and reflect back the same signal mixed with an FM chip, as to confuse the radar gun.

At very short distances (under two feet) this theory does work. If you were to attend an electronics or automotive trade show such as SEMA or CES, where Rocky Mountain Radar frequently sets up a display, you'll see that their radar jammer scrambler is within 12 inches of the police radar gun in their demonstration. Several people, including myself, have asked the RMR associates if they could place their radar jammer scrambler just a few more feet away from the radar gun to make sure that their product would still work, they will refuse. In fact, they have been asked this so many times, they have now encased their demonstration in a clear plastic box, to discourage others from asking.

When questioned why respected leaders in the industry like Radar Roy, Carl Fors, or Craig Peterson say and demonstrate on their website's that their products don't work, they come back saying that they are "paid guns" by other radar detector companies out to trash their products.

Active Radar Jammers

Active Radar Jammers are designed to emit their own radio signal on police radar bands and jam them. Some of the earlier active radar jammers for X and K band radar and were very effective. However when Ka band emerged, it became much more difficult because of the bandwidths spectrum. One company developed the Scorpion Ultimate Ka radar jammer that made attempts, however customers of this $1500.00 product have complained that the unit frequently goes out of band and that they had not been able to contact the manufacture back to have their unit re-calibrated.

Another pitfall of active radar jammers that they are illegal to manufacture, sale, ship, market or own in the USA by the Federal Communications Commission. Fines can run as high as $50,000 with prison up to five years.

Next we will discuss alternatives to radar jamming devices that really do work as advertised and can save you from an expensive speeding ticket.
