The FM repeater can be used with other spy tools, like the in-ear receiver, spy pen or spy microphone and with another FM transceiver, to enlarge the communication distance.
The FM repeater will have to be placed somewhere between the RF earpiece in-ear receiver and the other transceiver.
This is how a complete covert communication system looks with a transmitting range of 3000 m
