Which of the following is an acceptable method to determine that your station complies with FCC RF exposure regulations?

All of the methods mentioned for determining compliance with FCC RF exposure regulations are acceptable and valid approaches.

Calculating based on FCC OET Bulletin 65 is a key method, as this bulletin provides guidance for evaluating RF exposure levels and includes specific formulas and procedures that can be followed to ensure compliance with established limits.

Computer modeling is another accepted technique. This approach involves using software that simulates the RF radiation patterns and exposures based on antenna characteristics, power levels, and station configurations. This can help predict exposure levels and validate that they fall within safe limits.

Measuring field strength with calibrated equipment provides a direct assessment of RF exposure at your station. This can involve using an RF field strength meter to obtain actual measurements of the radiation in the vicinity of the station, giving a concrete evaluation of compliance.

Since all three methods—calculations from guidance documents, computational simulations, and actual measurements—can effectively demonstrate that a station meets FCC RF exposure regulations, the inclusive answer is that all of these approaches are valid for compliance determination.
