This report adds to the current boy of underground communications system design knowledge by: accurately defining (measuring) the 12 dB SINAD sensitivity of the system receivers and then stating the equivalent magnetic field strength in uA/m; showing that when a passageway repeater is used in loop to loop via the line communication link that the received signal level dependence in line current is only at the first power of distance; and maximizing the transmit magnetic moment is extremely important in the design of the transmit antenna network.
