General exam question G0B04
Subelement G0, ELECTRICAL AND RF SAFETY· Group G0B
Where should the station’s lightning protection ground system be located?
- A.As close to the station equipment as possible
- B.Outside the building (correct answer)
- C.Next to the closest power pole
- D.Parallel to the water supply line
WhyA station's lightning protection ground system should be located outside the building. A station's lightning protection ground system needs to intercept a strike and dissipate its energy into the earth before that energy has a chance to enter the building at all, so it belongs outside the building, as close to where conductors enter as practical, answer B. Placing it as close to the equipment as possible, next to the nearest power pole, or run parallel to the water line doesn't serve this outside-interception purpose, so A, C, and D are wrong.
