## Explanation

FCC Rule [§97.13(c)(2)](https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-97/subpart-A/section-97.13) requires amateur operators to ensure their station complies with the Maximum Permissible Exposure (MPE) limits. Operators are given flexibility in how they determine compliance, particularly for complex or high-power installations.

[Compliance can be determined in several ways](https://www.arrl.org/fcc-rf-exposure-regulations-the-station-evaluation): **calculation based on [FCC OET Bulletin 65](https://forum.openhamprep.com/t/e9h10-how-can-the-output-voltage-of-a-multiple-turn-receiving-loop-antenna-be-increased/845)**, **[calculation based on computer modeling](https://www.arrl.org/rf-exposure-calculator)**, or **measurement of field strength using calibrated equipment**. Thus, all these methods are permitted for determining compliance.
