🔍 Key Concepts

• RF exposure limits set by the FCC/USCG for marine radio sites • How percent of maximum permissible exposure (MPE) is used when summing multiple antennas at one site • Rules for when a source is included or excluded from the total RF exposure calculation

💭 Think About

• Think about why regulators would ignore very small contributors to RF exposure. What kind of small percentage threshold would make sense as a cutoff? • Compare each answer choice and ask: if several antennas are each just below this percent, could they still add up to a significant total exposure? • Which percentage seems like a practical engineering threshold used in many safety standards for deciding whether something is ‘de minimis’ (too small to matter)?

✅ Before You Answer

• Be clear on what maximum permissible exposure (MPE) means in this context. • Consider that the rule is about including antennas whose contributions are above a small fraction of MPE when calculating total site exposure. • Ask whether the threshold should be very tiny, moderately small, or quite large to be both safe and practical in real-world RF site design.
