This volume covers all aspects of radio and communications engineering from very low frequencies to microwaves, with particular emphasis on mobile communications. Wave principles and the decibel scale, instrumentation and power supplies, equipment types and encryption methods, and connectors and interfaces are all included in this book. While primarily a reference for those involved in the radio industry, this is also a handbook for students, amateurs, and anyone interested in radio and communications technology. The author has spent a lifetime working in radio, first in the armed forces and then with the emergency services. He was part of the team who developed the first personal radio for police, and several ground-breaking patents bear his name. He now lectures and writes on a wide range of radio topics. Previous books include "Private Mobile Radio - A Practical Guide"
