The Ubiquiti ETH-SP-G2 Ethernet Surge Protector is a compact and affordable solution for protecting outdoor network devices. It guards against damaging electrostatic discharge (ESD) and power surges.

With a plug-and-play design, it’s ideal for WISP networks, outdoor CPEs, and structured cabling systems.

The ETH-SP-G2 features two surge-protected RJ45 ports. It supports both PoE and non-PoE devices with speeds up to 1 Gbps.

Although Ubiquiti airMAX devices include built-in ESD protection, adding this device adds an extra safety layer. It helps ensure stable and long-term network performance.

For best results, install two surge protectors per setup—one near the CPE and one at the building’s entry point. This setup absorbs dangerous surges and safely discharges them into the ground, helping avoid service interruptions and costly damage.
