Q

Under which condition will a SART unit have the greatest transmission potential?

🔍 Key Concepts

• SART (Search and Rescue Transponder) operates on X‑band radar and must be detected by rescuing ships’ radar antennas • Line of sight and antenna height strongly affect how far radio-frequency signals can travel over the sea surface • How water affects radio antennas at 9 GHz compared with keeping the antenna clear and unobstructed

💭 Think About

• Think about how radar and VHF signals travel over the sea: does putting an antenna in the water usually help or hurt range? • In an emergency, rescuers need to detect you from as far away as possible – which option would most improve the radio horizon between your SART and the ship’s radar? • Consider what parts of a survival craft or the sea itself might block, absorb, or weaken radar-frequency signals.

✅ Before You Answer

• Which option gives the best line of sight between the SART and an approaching ship’s radar antenna? • Which options unnecessarily block or attenuate (weaken) the signal with water or structure? • Which option is consistent with how we mount other marine antennas (like VHF and radar) for maximum range?
