The document contains two questions related to leaky feeder applications in mining and calculating the gain and coupling of a leaky coaxial cable (LCX cable). The first question asks to summarize the application of leaky feeder systems in mining applications. The second question asks to calculate the gain and coupling of an LCX cable given the measured signal power from the cable, the signal power from the signal generator, and the free space loss over a 2m separation between antennas. No student answers or assessor feedback are provided.
