Where should a lightning arrestor be installed in a coaxial feed line?
At the output connector of a transceiver
Installing a lightning arrestor at the output connector of a transceiver is incorrect because it won’t protect the entire feed line going into your home, leaving your equipment vulnerable.
At the antenna feed point
While placing a lightning arrestor at the antenna feed point provides some protection, it is not the most effective method because the high voltage could still travel along the feed line into your home.
At the ac power service panel
Installing a lightning arrestor at the AC power service panel is irrelevant in this context, as this would only protect against voltage surges in the AC power lines, not in the coaxial feed line.
On a grounded panel near where feed lines enter the building
The correct answer is to place a lightning arrestor on a grounded panel near where feed lines enter the building, as this position ensures that high voltages are diverted to the ground before they can enter your home and damage your equipment.
Explanation
Understanding where to install a lightning arrestor in a coaxial feed line is crucial for the safety and longevity of your amateur radio equipment. Lightning strikes can deliver incredibly high voltage that can destroy radio equipment and pose significant safety hazards. By installing a lightning arrestor , you can divert these dangerous voltages to the ground before they reach your sensitive electronics. In the context of this question, the correct and safest place to install a lightning arrestor is on a grounded panel near where feed lines enter the building. This setup helps to minimize the amount of the structure within which dangerous high voltages could be present, thus offering the best protection for your equipment and for the safety of the property and its inhabitants.
