Ubiquiti Networks ETH-SP-G2 Surge Protector Surge Protector (500A, White, 80g, 91mm, 61mm, 32.5mm)

All of their items are good quality, easy to connect, and work well. I highly recommend Ubiquity. Great for work and at home.

Good little surge protector for Ethernet cable. Remember to use shielded ends bonded to shielded Ethernet cable.

It's a solid investment to protect your equipment from lightning strikes.

These help supress damaging voltage spikes from near lightning strikes. Install a suppessor on long ethernet cable runs. To be affective you will need to install a earth ground to a spressor.

Does what it says. Has saved indoor equipment on more than one occasion for me. If your rooftop radio gets struck by lightning it will get fried. These will not save it. They're not designed to. They're designed to keep the lightning from traveling down the ethernet cable and damaging the equipment on the other end. My only complaint to Ubiquiti is that they should provide a lug to attach the ground wire to rather than having to crimp a ring terminal to the wire, which adds an extra step to my install process. This is why I removed one star. Otherwise it's a great product at a very reasonable price.NOTE TO FIRST TIME USERS: You must install a ground wire or screw it to a grounded metal surface, otherwise it will not save your equipment. Without a ground it's just a fancy ethernet coupler.

Great product, truly an outdoor item. Tested it and has been outside for the last 3 months. Its amazing. No downtime at all.

Does its job

Plugs in easily. No impact on ethernet performance. Of course, I won't know if it works as a surge suppressor unless I get hit with a surge.Would be nice if it included a short ethernet cord.
