🔍 Key Concepts

• Search and Rescue Transponder (SART) operation and purpose • How line of sight affects radar and radio range • Effect of antenna height on detection range

💭 Think About

• Think about whether radio and radar signals travel better over long distances when the antenna is low to the water or high above it. • Consider what happens to range when you increase the height of either the ship’s radar or the target’s reflector/transponder. • Ask yourself which options affect signal propagation and which are just about orientation or power settings that may not exist on standard SARTs.

✅ Before You Answer

• Which option improves line of sight between the SART and the searching vessel’s radar? • Which choice is consistent with how we mount EPIRBs, antennas, and radar reflectors to increase range? • Eliminate any options that describe features or positions that are not typical of SOLAS-approved SART equipment.
