A device for monitoring the integrity of an antenna wire loop, such as for a pet containment system, and a system using the monitoring device are disclosed. The device can be incorporated in the transmitter portion of the pet containment system or can be a stand-alone device electrically and operationally coupled thereto. The device includes a current monitoring portion that monitors the current driven in the antenna wire loop and a display portion that displays the intensity of the electromagnetic field in appropriate units, such as feet.
