Body Wires are body worn transmitters carried by a person to covertly transmit a conversation to a radio receiver. Body wires tend to be more powerful than room transmitters, as a body wire generally use crystal controlled frequencies for improved transmission stability. Using body wires and body wire transmitters give the user the ability to transmit using extended distances, as body wires generally tend to have longer antennas compared to room transmitters.

Q: Is a body wire transmitter better than a room transmitter?

A: Body wire transmitters tend to have greater power output compared to room transmitters. However, body worn transmitters work best if the user does not move around as much. The less the movement, the more focused the radio signal will be during transmission. This involves the principle of compensation when a crystal controlled transmitter is in operation.
