Question
What should be done if evaluation shows that a neighbor might experience more than the allowable limit of RF exposure from the main lobe of a directional antenna?
Answer Options
- A) Change to a non-polarized antenna with higher gain
- B) Use an antenna with a higher front-to-back ratio
- C) Take precautions to ensure that the antenna cannot be pointed in their direction when they are present
- D) All these choices are correct
Correct Answer: C
Explanation
If an RF exposure evaluation determines that the main lobe of a directional antenna might expose neighbors to levels above the MPE limit, the operator is obligated to prevent that exposure. The most practical and effective step is to control the antenna’s direction.
The necessary precaution is to take precautions to ensure that the antenna cannot be pointed in their direction when they are present. This can be achieved by using physical stops or mechanical locks on the rotator, or by employing software controls that limit the azimuth sweep to exclude the direction of the neighbor’s property or house.
