Contract/MOA Report - April 1981

U.S. Bureau of Mines Contract No. J0308012-1, 1981; :1-47

This report presents test results, data evaluations, and typical system performance expectations based on wireless electromagnetic propagation measurements performed in the MAGMA Copper Company San Manuel mine near Tucson, Arizona during March 30 through April 2 1981. In particular, and at the Bureau's request, this work was coordinated with testing of MF prototype vehicular radios being developed by A.R.F. Products, Inc. with USBM support under Contract H0308004 as part of a system to be marketed by Mine Safety Appliance Co. This testing also employed a prototype vehicular antenna developed by Terry S. Cory, P.E. with USBM support under previous Contract P0382223.
