C'mon using a Lo-Jack receiver is too easy! :lol: :wink: I rather use a beam antenna and the basic triangulation method to figure were that signal is coming from. I guess the triangulation method will only work if that transmitter/car is stationary.


Here is this LoJack audio file on this page.

You cannot purchase one normally. I saw one that was on an Ebay auction that went for about $800, but that's the only one I've ever seen. They are normally not on the market to preserve the technology and equipment, someone said that Lojack retains ownership and will not allow them to be sold or traded - they simply install it in the police car and then come get it back when the car is taken out of service. But, just what I've heard.

I don't believe the cars that are equipped with the device transmit until the system tells the car it's been stolen and to start transmitting, but I might be wrong. As for hearing the police cars, that won't happen either - it's just a receiver.

RolnCode is correct, they Lo-Jac system will not transmit anything until the car is reported stolen. After being reported stolen, the veh/motorcycle/trailer etc will then start transmitting. Depending on the terrain etc, I believe the units can be picked up within a 5 mile radius.

From what I have heard it is much harder for ground units to determine where the stolen veh is, I know my city has select units running the Lo-Jack receiver along with the heli. Usually the heli is the one to find a signal first by flying around town on other calls.

No. The Lo-Jack equipment in their cars are receive only. Lo-Jack controls the transmitters that activate the equipment in the 'stolen' cars.

Reason I asked was that occasionally I've heard transmissions between what seems some law agency (possibly our college security/police) using that frequency with a PL tone of 100.0. Maybe they are using an unauthorized freq.

Another tidbit, initially, the vehicle only transmits once every minute or so once it's been reported stolen.

After law enforcement receives the first transmssion, and runs the lojack code through CLETS, it begins transmitting more frequently (every 30sec, I think)

A previous poster was correct when they said that lo-jack installs the receivers in police vehicles and aircraft for free and they retain ownership. They then remove the equipment when the police vehicle goes out of service.
In recent years they have drastically ramped up use in southern border areas and ports. I know almost all of the border sheriff's departments, DHS, and border cities have at least 1 lo jack unit in Texas now.
Almost all of the Texas DPS choppers have them now as well.

It really just depends on what part of the country you are in. In the Northeast lo-jack has a very good presence, in the southeast there are significant gaps in LE coverage due to so many rural areas.

Ive used lo-jack myself and it works better when more than one patrol car is tracking the signal and when the target is stationary. If a target is just passing through a city on a highway a signal will appear then go away with no time to figure out where it is.
The first target I had was a stolen bob-cat tractor which was parked in a garage at a business. It took about 30 minutes with two patrol cars to narrow down the location, which allowed us to get a search warrant.
So much of what lo-jack does now are motorcycles, boats, and especially heavy equipment like bulldozers.

You would think in this day and age of high sensitivity miniature gps it would be cheaper and easier to just encode lat / long and drive right to it.
