Input

The transmitter is mounted in and powered from a vehicle. The antenna is mounted on the

vehicle's roof. Preferably placed in a location free of other metallic objects. The dual band

antenna receives a properly coded activation signal from a receiver. The diplex filter routes

the activation signal to the activation receiver. The activation decoder determines a code

match between the received signal and setting of the transmitter. If a code match occurs, the

decoder activates the transmitter enable switch. Otherwise the transmitter remains powered

off. The transmitter enable switch causes the transmitter to power on. The test signal is feed

to the dual band antenna by the diplex filter. The diplex filter prevents the test signal from

being routed to the activation receiver.
