More Information


The Ubiquiti ETH-SP-G2 is designed to protect PoE and non PoE devices with a connection speed up to 1 Gbps, against electrostatic discharge and surges that can cause damage to internal components.

Ideal for WISP Networks

Although all Ubiquiti airMAX devices include ESD protection pre installed, the ETH-SP-G2 offers further protection to outdoor devices and can help meet local code requirements.

The Gen 2 models provide all the features of the first generation, but with significantly better surge protection performance. 

The ETH-SP-G2 comes with two passive, surge-protected RJ45 connections provide maximum equipment compatibility.

Installation is quick and easy with either pole or wall mounting available, and the plug and play design ensures hassle free set up.


Hardware Overview
