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.

Body Wire Transmitter technology is based on the need to collect intelligence manually, with the user present and / or a part of the conversation being monitored. Therefore, the cause for a body wire transmitter to be hand carried or body worn is based on the requirement that a listening device be made portable for field operations.
