Plain-language answer: An RF exposure evaluation documents whether the complete station remains within current exposure limits for people who can access the area.
Why the definition matters
The evaluation must include every relevant transmitter and antenna, actual or conservative power, feed loss, gain and pattern, frequency, duty cycle, distance, and simultaneous operation.
Use the number correctly
Start with the regulator’s current method, draw accessible areas, calculate a conservative case, add contributions where required, and verify controls such as signage, barriers, or reduced power.
The common mistake
Evaluating only the main HF antenna while ignoring other transmitters or publicly accessible directions.
Measurement and safety boundary
Keep reference units, bandwidth, detector, direction, averaging, and test conditions attached to every number. Current regulator requirements and the complete installed system control RF-exposure compliance.
