LoJack的上173.075兆赫的无线电（RF）载波频率进行发送。 车辆与系统安装发送一个200毫秒（ms）啁啾每十秒就这个频率。 当报失之后被跟踪，设备发出一个200毫秒的信号每秒一次。 通过LoJack的发射的无线电频率是接近的VHF谱带以前用于北美由模拟电视频道7，虽然有最小的干扰，由于辐射，简短啁啾持续时间，和线性调频脉冲之间的时间间隔长的低功率。

LoJack transmits on a radio (RF) carrier frequency of 173.075 MHz. Vehicles with the system installed send a 200 millisecond (ms) chirp every ten seconds on this frequency. When being tracked after reported stolen, the devices send out a 200 ms signal once per second. The radio frequency transmitted by LoJack is near the VHF spectrum band formerly used in North America by analog television channel 7, although there was minimal interference due to the low power of radiation, brief chirp duration, and long interval between chirps.
