The primary vendor for tracking devices in our area, the Pacific NW, is ETS, which is a division of Spectrum Management. They would be able to provide you with specifications for their product and tell you if your local law enforcement agency participates in their program. (If they don't the tracking devices are moot.)
Here is a weblink for Spectrum/ETS
