Product Description

The destructive power of thundering is extremely large. It is not enough to rely on external thundering protection ( thundering rod). Thundering waves will indirectly or indirectly (through electromagnetic induction) invade electrical passages and metal passages (such as power cables, signal cables, antenna feeders and metal pipes). The resulting thundering overvoltage and surge voltage will cause great harm to electrical equipment, and information network systems. If the cables is damaged, the equipment will be damaged and the system will be paralyzed, resulting in an incalculable loss.

5.0 out of 5 stars Works really well passing ethernet signal
By Dr. Ronald K. Wright on August 3, 2019
I had tried 2 other lightning arresters. One switched the signal from 4 to 5. The other, did not switch any signals, but would not work in my setup. Perhaps I should explain my set up. I have a micro wave antenna which captures a signal from my ISP and converts it to an Ethernet signal. We live on a mountain in Tennessee which is often struck by lightning. Therefore, I really need lightning protection on any wired connection. From the ethernet signal from the antenna I connect with an ethernet 8 rj45 unmanned switch which supplies my EERO gateway and the fiberglass connection to my office. The other 2 arresters would not work. This one seems to pass the ethernet signal flawlessly.
It is not connected to ground. All of the other 2 are connected to ground. Whether it will protect against lightning I do not know. When we have another storm with cloud to ground lightning I will report again. Amazon lets one add to reviews.
