Where should a lightning arrester be installed in a coaxial feed line?
At the output connector of a transceiver
At the antenna feed point
At the AC power service panel
On a grounded panel near where feed lines enter the building✓Правильный ответ
Объяснение
The arrester's job is to divert surge energy to the grounding system before it reaches the building and the equipment inside, so it belongs on a grounded entry panel where the feed lines come in. Mounting it at the transceiver or the antenna would let surge current travel through the building or bypass the ground point.
