Query: Too complicated for no reason

This book is too complicated for absolutely no reason. The author assumes every reader has a PhD in Mathematics. I work in the satellite broadcast industry and have this book in addition to "Principles of Communications Satellites" by Gary D. Gordon and Walter L. Morgan. If you are interested in learning about the satellite industry, dabbling with actual link budgets with formulas and examples that you can enter on your computer immediately to create an up/down link budget (via Excel), then do yourself a favor and buy the book I endorse above, you will be much happier.
