How can a SART's detection and effective range be maximized?

Mounting a Search and Rescue Transponder (SART) as high as possible and in a vertical position is essential for maximizing its detection and effective range because radio waves propagate differently depending on their placement. When a SART is raised higher, it has a greater chance of being detected by search radar from vessels or aircraft that are also at a distance. This increased elevation helps to overcome obstacles such as waves or an uneven sea surface that could block the signal.

Positioning the SART vertically ensures that its radar signal can spread unobstructed in all directions, giving the searching craft a better chance of receiving the signal due to the direct line of sight. This approach is aligned with the principles of effective communication and radar tracking, where height can dramatically enhance signal performance.

While other choices may seem relevant, such as placing the SART directly in water or switching to a high power position, those do not emphasize the importance of positioning for optimal detection. The transient operation of a SART is crucial, but its elevation and orientation relative to the expected radar waves take precedence in ensuring reliable communication during search and rescue operations.
