PREFACE

By enrolling in this self-study course, you have demonstrated a desire to improve yourself and the Navy.

Remember, however, this self-study course is only one part of the total Navy training program. Practical

experience, schools, selected reading, and your desire to succeed are also necessary to successfully round

out a fully meaningful training program.

COURSE OVERVIEW : In completing this nonresident training course, you should be able to: discuss

wave propagation in terms of the effects the earth’s atmosphere has on it and the options available to receive

optimum performance from equipment; identify communications and radar antennas using physical

characteristics and installation location, radiation patterns, and power and frequency-handling capabilities.

Be familiar with safety precautions for technicians working aloft; and discuss the different types of

transmission lines in terms of physical structure, frequency limitations, electronic fields, and radiation

losses.

THE COURSE : This self-study course is organized into subject matter areas, each containing learning

objectives to help you determine what you should learn along with text and illustrations to help you

understand the information. The subject matter reflects day-to-day requirements and experiences of

personnel in the rating or skill area. It also reflects guidance provided by Enlisted Community Managers

(ECMs) and other senior personnel, technical references, instructions, etc., and either the occupational or

naval standards, which are listed in the Manual of Navy Enlisted Manpower Personnel Classifications

and Occupational Standards , NAVPERS 18068.

THE QUESTIONS : The questions that appear in this course are designed to help you understand the

material in the text.

VALUE : In completing this course, you will improve your military and professional knowledge.

Importantly, it can also help you study for the Navy-wide advancement in rate examination. If you are
