View Full Version : Dash Mount Jammer Feasible?

I´ve been thinking a lot lately about a dash-mounted jammer that would continuously send out a laser signal. Would that work and actually jam the guns?
If this would work Blinder, Escort, Bel, lidatek, target, Antilaser, and Laser Mimic would have dash mounted models because it's easier to just stick something on your dash. Remember, you can't always detect laser with a radar detector. That is because your radar detector is too high up from the target area of your license plate.

Dash mounted laser jammer can be done but it would probably cost twice as much as the usual laser jammer. The reception would have to be boosted like 10x, than the noise would start popping off false alerts so you would have to add more filters to receiver. The jamming source would also have to be 10x more powerful (laser d. probably). Big lenses should be emplaced in front of receiver and transmitter. All that adds to retail price

OK, how about getting a couple of laser gun diodes and mounting them inside the grill? Could they operate full time?

Your not going to jam anything with a IR LED running full time. Each manufacture uses different blinking speed; and you would have to match the blinking speed. RMR seem to use LED's running full time, but they don't jam anything.
There is a show on TV (discovery channel) called Mythbusters. They made over 100 IR led's shine on a lidar gun, and it didn't jam. The LED's must blink in order to jam!

I meant the laser gun diodes, not the LEDs, but good info nonetheless. I haven´t seen that episode, would be interesting.

That episode was actually one of the most retarded things I've ever seen on there...

The RMR scrambler units do have a permanent-on IR bulb...

You must have a receiver in a device to be a succesfull jammer. The so called stupid jammers without receivers actualy work on some lasers like the LaserPatrol but they bring on the JAMMED error, and that i s not very good in Europe! Laser diodes can't be turned on all the time, they need the time to chill so you dont have coverage for that time that they are cooling off and that is just the time when the lidars measures you and your jammer fails in jamming.

Ok, thanks for the clarification. It sucks when jammers are prohibited and you need both an undetectable and completely concealable jammer...
Antilaser ,
this is a quote from one of my post , do you think it is feasible :
original post : http://www.radardetector.net/viewtopic.php?p=20367#20367
''About using headlight as an amplifier for jamming laser?
Everybody agree that headlight is the second strongest
laser reflector.
If one could install inside the headlight a mini jammer ,
with the amplification induced it could be made smaller.
Instead of introducing the jammer itself , why not using
optic fiber cable to transport
the signal inside the headlight by introducing just the tip
of the cable thru small hole made in the headlight shell.
Fiber Optic Digital Audio Hookup
Benefits :
With this idea ,
1) only one emitter can be used to send the signal thru
the 2 headlights via a splitter.
2)amplified signal .
3) stealthiness would be greatly augmented.
4) because strong
law prohibiting laser jamming are coming soon , the other side
dont want to lose money.Those laws exist in many places but
the pressure to enforce them will come sooner than we think.$$$$$$$$ ''

Optic fiber is not a bad idea. Many new lidars use optic fiber infront of laser diode to boost the signal. But 900nm fiber is not readly available in every RS not to mention the price of it. Again you could double the price of a usual jammer to get a rough estimate of a price of sucha stealth version. But generaly not a bad idea! 8)

Ok, any news on this? I´d love to have the first laser-jamming car :mrgreen:

Anyway, an idea. Jim has said that his signal decoder for the V1 could be used to trigger other devices. So one could hook up a laser detector (same as used by the V1) inside the grille and hook it up so it would trigger the laser diode, hooked up to the headlights. That would make for one heck of a stealth laser jammer.
