Are there any Laser/Radar Jammers out there?? Affordable? If not, any of you guys have radar detectors? Are they worth it?

Go over to http://www.carsound.com and do search in Richard Clark's forum. There was a post there a couple months back. That Richard told which one's actually worked and which one's were a waste of money. Sorry I couldn't be more help :)

passives can't work do to a thing called punch through---it is the strength of the jamming signal/real signal. a passive would have to have the antenna wrapped all up and down the car to get a good amount of signal to jam

well, I heard of these Phantom Jammer/Detectors. Got any opinion on them?

Got any opinion on them? it passive and doesn't work for the reason in my post above-------if you want a radar jammer you have to have an active one-------you know you turn it on and everybodys radar detectors go nuts--------though laser is a diferent story-----you can do a little to guard against it. no front license plate -----rear defuser over your license plate-----and matbe an active laser jamer

I've heard many mixed thought/opinions about jammers. Some swear by them and some say they are better for a paper weight. Check out K40 detectors. They have a pretty nice guarantee on them. I think they will pay the ticket if you get one. I wouldn't get a jammer for the fact that they are such a crap shoot. It all depends on how you're getting clocked (front, back, angled, etc.).

It all depends on how you're getting clocked (front, back, angled, etc.). there isn't any opinion on them--------they can't work ----read some radar ECM design books. the math very clearly state a PASSIVE system isn't going to jam anything. the power directed at the car is reflected by the car body---motor. the tinny--tinny antennea picks up a very very very small fraction of the energy the unit REraidates it back out in a unfocused manner. That means that only a very small amount was picked up and now only a faction of the REraidated energy is being sent back in the direction of the cop's radar gun. The signal to noise ratio is going to be EXTREMLY large. the real reflected signal from the car will STOMP OUT the jamming signal. you would have to put the passive jammer----IN the cops RADAR gun to EVEN start to be effective. as you really want a higher jamming signal level when compared to the real return signal. ----------whats the sense of having the company pay your first ticket ------if it is the insurance that kills you----------the angle of the energy doesn't matter to a jammer because the jammer "rings" all the filters so the gun can't see the real signal.

For one you cant have a "Radar Jammer". The FCC wont allow them. The only products that you can have are laser jammers which do work. There are however many junk ones. You want one that works then buy one from rocky mountain radar. The jammers only work if the cop that tags you is running instant on laser and not radar(which most still use).

Ok Ok OK, enough w/ the Scientific crap what the question is if I'm speeding and i see a cop is there anything that i can buy to jam his radar?

No, there isn't. If he is using laser then yes, you can. Otherwise get yourself a good radar detector and hope he tags someone in front of you so you know he is there. Also, you can use the other approach and just don't speed. The best radar detector out there that I have seen is the valentine one.

- Steve I have some books on it-------- some basic electrical/physics classes would be needed

though the idea is simple ------ output a signal that rings all filters at once than the gun can tell the real speed

Ok I'll try and look for some things on the net...I teach an electronics class so I have the knowledge, just need a parts list and PCB blueprint.

ok ok I have not been around in a while but hapen to have a LOT of experience working with various types of radar equipment. The best and only way you are going to jam a signal is with a higher signal. In which case many cops know it is not right because it would **** up the system and they would probably notice you speeding and do a manual clock on you. IF it were that ****in easy to jam a radar system of any sort it would be used voer stealth technologies in the military. Fact of the matter is. It is not so easy to do and the amount of equipment necessary in a vehicle to do it other than stealth materials and body design would probably not do much good.

what if a cop still pulls you over and noticed you had a radar detector couldent he give you a ticket anyway based on a estamated speed and im not talking barely going over the speed limit i mean clearly going over the speed limit
