Where should a lightning arrester be installed in a coaxial feed line?

• A. At the output connector of a transceiver
• B. At the antenna feed point
• C. At the ac power service panel
• D. On a grounded panel near where feed lines enter the building

Answer: (D)

Installing a lightning arrester on a grounded panel near where feed lines enter the building is the most effective placement for protecting your equipment from lightning strikes and surges. This location provides an essential barrier that diverts the energy from a lightning strike directly to the ground before it can reach sensitive components like your transceiver or antenna. By positioning the arrester close to where the feed lines come into the building, it minimizes the risk of voltage surges traveling along the coaxial cable and affecting your equipment. This is crucial because coaxial cables can conduct electrical currents, and if a surge were to enter through the cable due to a lightning strike, it could cause significant damage. While placing an arrester at the output connector of a transceiver or at the antenna feed point may seem beneficial, these locations would not effectively ground the surge as close to the point of entry as possible, leaving the system more vulnerable. Installing it at the AC power service panel also does not address surges traveling through the coaxial feed line specifically, which could lead to damage before the energy reaches the power panel. Thus, having the arrester at the appropriate point near the entry ensures that the system is adequately protected from outdoor electrical disturbances.
