Critical Tasks: 01-5705.07-0003
In this lesson, you will learn about the fundamentals of radio wave propagation, modulation, and
propagation characteristics through different media.
TERMINAL LEARNING OBJECTIVE:

For many, radio is a mysterious phenomenon that only technicians understand. All signal officers must
be able to describe the nature of radio wave propagation and the forces that impede or enhance a radio
signal. The more you know about how radio behaves, the better able you will be at providing reliable
signal support, especially when faced with unexpected challenges.
