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

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

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

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

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.

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.

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.

When installing an antenna or access point outdoors, DO NOT SKIP surge suppression. This (type of) device is essential for protecting your equipment from damaging and dangerous electrostatic discharges and lightning strikes. While not guaranteed to completely eliminate damage due to these events, a quality surge suppressor can significantly limit the damage and help reduce dangerous conditions.

What can I say, this surge suppressor was just what I was looking for. I had a wireless internet service coming out to my house, and wanted to make sure I installed on of these to protect my equipment inside from lightning. Of course, I haven't had any lightning strikes, but this product does help provide that peace of mind. I will update if its durability is ever tested. I will say, I wish the grounding was a bit better, like a double nut setup, but it works....
