What precaution should be taken if you install an indoor transmitting antenna?
The correct answer is C: Make sure that MPE limits are not exceeded in occupied areas. The precaution that should be taken if you install an indoor transmitting antenna is to make sure that MPE limits are not exceeded in occupied areas. Indoor antennas can create high RF exposure in occupied spaces, so you must ensure limits aren't exceeded. For amateur radio operators, this is critical for safety. Understanding this helps ensure safe indoor operation.
Exam Tip
Indoor transmitting antenna precaution = ensure MPE limits not exceeded in occupied areas. Think 'I'ndoor 'A'ntenna = 'I'mportant to 'A'ssess MPE limits. Indoor antennas can create high RF exposure, so you must ensure limits aren't exceeded. Not close location, not wall edge, not shielding - just MPE limits.

Real-World Application
You install an indoor transmitting antenna. Indoor antennas can create high RF exposure in occupied spaces (rooms where people are present). You must evaluate RF exposure and ensure MPE (Maximum Permissible Exposure) limits are not exceeded in occupied areas. This is the critical precaution - ensure MPE limits aren't exceeded. This ensures safe indoor operation.

Why Other Options Are Wrong
Option A: Incorrect. Locating antenna close to operating position doesn't minimize feed-line radiation - it might increase exposure. Close location isn't the precaution.
Option B: Incorrect. Positioning antenna along wall edge doesn't reduce parasitic radiation - it doesn't address RF exposure. Wall edge isn't the precaution.
Option D: Incorrect. Making sure antenna is properly shielded doesn't address RF exposure - shielding might help, but MPE limits are the key. Shielding isn't the primary precaution.
