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?
- 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 (correct answer)
- D.All these choices are correct
WhyIf a neighbor might experience more than the allowable RF exposure limit from a directional antenna's main lobe, precautions should ensure the antenna cannot be pointed in their direction when they are present. If an evaluation shows a directional antenna's main lobe could expose a neighbor beyond the permissible limit, the practical fix is to physically prevent the beam from being pointed at them while they're present, whether through rotator limits, scheduling, or similar operational control, answer C. Switching to a higher-gain antenna or one with a better front-to-back ratio doesn't solve the specific problem of the main lobe itself pointing at an exposed area, so A and B don't fix the issue, and since they don't, D's "all of these" is wrong too.
