*Question G0A11:
What precaution should be taken if you install an indoor transmitting antenna?*  

*Correct Answer is  C: Make sure that MPE limits are not exceeded in occupied areas*  

### AI Response: (may contain errors)  

When installing an indoor transmitting antenna, it's crucial to consider safety, particularly regarding exposure to electromagnetic fields (EMF). 

### Correct Answer: C - Make sure that MPE limits are not exceeded in occupied areas

- **Explanation**: MPE stands for Maximum Permissible Exposure. These limits are established to protect individuals from harmful levels of RF radiation. When installing an indoor antenna, you must ensure that the RF exposure does not exceed these limits in areas where people may be present. This is essential for safety and compliance with regulations.

### Why the Other Choices are Incorrect:

- **A: Locate the antenna close to your operating position to minimize feed-line radiation**  
  - **Explanation**: While minimizing feed-line radiation is a consideration, it does not address the primary concern of safety regarding RF exposure. Proximity to the operating position does not inherently ensure safety from MPE limits.

- **B: Position the antenna along the edge of a wall to reduce parasitic radiation**  
  - **Explanation**: Positioning the antenna along a wall may help with some radiation patterns, but it does not guarantee that MPE limits will be respected. The focus should be on ensuring safe exposure levels rather than just minimizing parasitic radiation.

- **D: Make sure the antenna is properly shielded**  
  - **Explanation**: While shielding can help reduce unwanted radiation, it is not a primary precaution for indoor antennas. The key concern is ensuring that the RF exposure remains within safe limits, which shielding alone does not guarantee.

### Useful Rules of Thumb:

- Always refer to the FCC's guidelines for MPE limits, which can be found in their regulations.
- Use RF exposure calculators or measurement tools to assess the field strength around the antenna.
- Maintain a safe distance from the antenna based on its power output and gain to ensure compliance with MPE limits.

By focusing on MPE limits, you prioritize safety in your antenna installation, which is the most critical aspect when operating in occupied areas.
