The Ubiquiti ETH-SP-G2 is a Gigabit Ethernet surge protector that shields outdoor network gear — gateways, radios, and PoE devices — from ESD strikes and power surges on the Ethernet line. Installed inline at the building entry point, it shunts surge energy to ground before it can reach expensive electronics.

Key specifications

• Inline surge protection for 10/100/1000 Mbps Ethernet links
• Protects PoE-powered devices (gateways, access points, cameras)
• Outdoor-rated, UV-resistant housing for exterior mounting
• Grounds surge energy via dedicated ground wire connection

Cheap insurance for any rooftop or tower-mounted gateway installation.
