Industrial Plastics: Theory and Applications

This is an ionospheric propagation assessment program that computes Maximum Usable Frequency (MUF) and Lowest Usable Frequency (LUF) for a user-defined sunspot number (or 10.7-cm flux) and X-ray flux. With this book the reader can quickly and easily determine the optimum frequency and best time for broadcasting to a particular area of the world. the MUF, LUF and Frequency of Optimum Transmission (FOT) versus time-of-day for a 24-hour diurnal period. Another shows coverage for any single frequency and time of day on a world map.
