Overview

This module will cover basic antenna theory, including directional and omnidirectional antenna selection. In general, high-gain antennas direct energy more narrowly and precisely. Low gain antennas direct energy in a broader, wider pattern. Everything about antenna choice involves a tradeoff. If maximum range is desired, coverage must be traded. With a directional antenna, the same amount of power reaches the antenna, but the antenna design can reflect and direct the RF energy in tighter and stronger waves, or wider and less intense waves, just as with a flashlight.

After discussing antenna theory and types of antennas, cables, connectors, and accessories for antennas will be discussed. With cable, the shorter the length, the higher the quality of coverage. Additionally, important antenna design considerations, such as link engineering, path planning, and installation are also discussed.
