Jammers dont work by blocking any reflections from you vehicle.

That's what I'm talking about. The signal of a jammer could be even weaker than the signal which is come from Lidar and is reflected from the plate...
That's why I'm thinking about how to make the front plate less reflective.

It has nothing to do with how a Jammer works. Your plate will be no issue and a Jammer does not effect the reflection going back to the gun. It expects that reflection to go to the gun.

Ok, what do you think about an assertion which can be found on the radartest.com:
"The laser jammer's task is easiest when it's trying to protect a dark vehicle wearing no front license plate." ?

Anyway, I hope I understand what you are going to say, good Jammer should cope even in such circumstances (with retro-reflective front plate).

Maybe with old guns.. Today's guns I dont see any difference with the color of the car. Sure protecting a car with no plate is easier because in general its harder to get a lock on it but we are not talking about trying to protect a car with passive countermeasures. When releasing and testing Jammers they are tested for the worse case scenario and that always includes a Front License plate. A jammer is not trying to deflect or stop the return signal from the gun like a passive counter measure. Its about timing and getting returns to the gun quicker then the expected pulse and confusing the gun.

Any jammer should be able to jam the gun even if it's firing into a mirror. Period. Jamming is about timing, not about power. It should not matter if the original signal from the gun is reflected back at 100% power; the jammer should still work.



If the gun is getting a punchthrough, the jammer is:
1. Not properly installed
2. Not "seeing" the gun (heads are too far from where the signal is currently falling and you need more jammer heads to cover the car)
3. Not updated to jam the gun being fired

In this case, it would be to your advantage to reduce reflectivity, but only because the jammer is deficient. You're still going to get tagged at some point and you need to upgrade/reinstall your jammers.

That's what I'm talking about. The signal of a jammer could be even weaker than the signal which is come from Lidar and is reflected from the plate...- performance defense is not dependent on the signal strength "difference" or "equality" of the 2 signals. Even if it were so,remember the Lidar signal has to make 2 trips (out to the target & then return to the Lidar gun,thus making the IR signal weaker in strength... the Parking Sensor has to make only 1 trip to the Lidar gun.

That's why I'm thinking about how to make the front plate less reflective.

Making the LP less reflective does help. "Tilting" the LP forward also helps a little causing some reflections to be directed to the road surface. Some 3M films do cause "diffusion" & scattering of the IR photons which also helps. I use both of these tactics on my LP !

"Tilting" the LP forward [...] 3M films do cause "diffusion" & scattering of the IR photons which also helps.

1. Which 3M film do you recommend ?
2. What I've noticed about my LP - the retro-reflecting effect makes my hand whole red back, even If I point by a toy, red laser from angle bigger than 45 degree !
And there is my question if tilting the LP could help in that kind of retro-reflective material ?
3. I think about tilting the front plate up. Why? Every time a LEO shoots me, I was on the top of a hill and the LEO was in the valley.

RR, Can you possibly provide info or a web link for the 3M film you use, please. Thanks, "JoisyGuy''

Currently I'm using 3M Scotchcal "Marking Film".
However,I'm looking for something even better. I noticed the 2 URL links that member "hussein" mentioned in his Post #1 that have interested me, but until I can acquire one or both to test I cannot recommend either one at this time.
