General exam question G0A11
Subelement G0, ELECTRICAL AND RF SAFETY· Group G0A
What precaution should be taken if you install an indoor transmitting antenna?
- A.Locate the antenna close to your operating position to minimize feed-line radiation
- B.Position the antenna along the edge of a wall to reduce parasitic radiation
- C.Make sure that MPE limits are not exceeded in occupied areas (correct answer)
- D.Make sure the antenna is properly shielded
WhyInstalling an indoor transmitting antenna requires making sure MPE limits are not exceeded in occupied areas. An indoor transmitting antenna sits much closer to people occupying the same building than an outdoor antenna typically would, so the essential precaution is confirming that MPE (maximum permissible exposure) limits aren't exceeded anywhere in the occupied space around it, answer C. Locating the antenna near the operating position, positioning it along a wall, or shielding it don't by themselves guarantee occupied-space exposure stays within limits, that has to be actually evaluated and confirmed, so A, B, and D are wrong.
