System and method for transmitting messages between first and second software components such as application software and software of a platform for a product. The method uses a modified early-minus-late correlation function to determine the code phase error between a target pseudorandom noise code of an incoming signal and locally generated replica codes. The mask prevents etchant from etching an area within a dielectric material near a conductive plug. The fluororesin insulation covers the central conductor such that all of the twisted single element wires of the central conductor contact the fluororesin insulation.
