🔍 Key Concepts

• Difference between radio frequency (RF) radiation and ultraviolet (UV) rays • Typical power levels and radiation pattern of INMARSAT-A/B dish antennas vs INMARSAT-C antennas • How automatic transmission might create a hazard if someone is close to an antenna

💭 Think About

• Think about which INMARSAT equipment uses a high-gain directional antenna (dish) and what that implies for exposure risk. • Consider whether a small, low‑power data terminal is more or less likely to be a radiation hazard than a large voice/data terminal. • Ask yourself which answer choices confuse UV filtering or "omnidirectional" coverage with actual safety from RF exposure.

✅ Before You Answer

• Verify which INMARSAT systems use dish-type, high‑gain antennas on many vessels. • Check whether INMARSAT-C is known for low power, omnidirectional operation rather than a tight, focused beam. • Confirm that antennas which can auto-transmit without operator action may pose a hazard if someone is standing very close in the main beam.
