Your Indispensable Bodyguard for Outdoor Networks
Your external Network devices are defenselessly exposed to the elements. Whether Ubiquiti airMAX Access Points, UniFi cameras, or wireless bridges – all are susceptible to electrostatic discharges (ESD) and overvoltages. The Ubiquiti ETH-SP-G2 is your reliable Ethernet Lightning Protection, which addresses precisely this. It acts as a barrier that dissipates dangerous voltage spikes before they reach your sensitive hardware. Imagine how much trouble and cost you save if your devices run stably and securely even under adverse conditions and your entire Network is protected.
Protection that Pays Off – Even Without a Direct Lightning Strike
You might think an Ethernet Surge Protection is only relevant for direct lightning strikes. But far from it! Even a nearby thunderstorm can cause induced voltages on long Ethernet Cable runs, damaging your devices. The ETH-SP-G2 not only protects against these induced voltages but also against static discharges caused by wind or dry air. In addition, it helps you meet local building codes for Outdoor Surge Protection and provides an additional layer of protection, even if your Ubiquiti devices already have integrated ESD protection.
Maximum Performance, Maximum Protection – for Your Gigabit Network
Many protection devices slow down your network. Not the Ubiquiti ETH-SP-G2! It is fully Gigabit Surge Protector-capable and supports network speeds of up to 1 Gbps, with some sources even mentioning 2.5 Gbps. This means you can confidently use it for your high-performance applications such as 4K cameras or fast wireless bridges. It protects all 8 wires of the network cable and allows PoE (Power over Ethernet) to pass unhindered, making it the ideal complement for any PoE Protection Device.
Two are Better Than One: Optimal Installation for Comprehensive Security
For truly comprehensive Network Lightning Protection, Ubiquiti recommends installing two ETH-SP-G2 devices per cable run. Place one near the outdoor device to dissipate static charges directly at the source. Install the second device at the building entry point to provide Network Device Protection for your internal network. Remember: The full functionality of the Ethernet Lightning Arrester is only guaranteed with proper grounding. Ensure a solid connection to a grounded metal pole or an equipotential bonding bar to optimally protect your infrastructure.
Strengths & Notes at a Glance
- Pro: Cost-effective and effective protection for expensive outdoor Ethernet devices against ESD and overvoltages.

Frequently Asked Questions (FAQ)
What is the Ubiquiti ETH-SP-G2 used for?
You use the Ubiquiti ETH-SP-G2 to protect your outdoor Ethernet devices, including those with Power-over-Ethernet (PoE), from harmful electrostatic discharges (ESD) and power surges. It provides an additional layer of protection for your outdoor network infrastructure.
Do I need to install two ETH-SP-G2 devices per cable run?
For optimal protection, especially for longer cable runs or to comply with regulations, it is recommended to install two ETH-SP-G2 devices: one near your outdoor device (e.g., CPE) and another at the building entry point to dissipate induced voltages from both sides.
Does the ETH-SP-G2 protect against direct lightning strikes?
No, the ETH-SP-G2 is primarily designed to protect against electrostatic discharges and power surges caused by nearby lightning strikes or other electrical events. It cannot intercept a direct lightning strike.
Is the ETH-SP-G2 compatible with Gigabit Ethernet and PoE?
Yes, the ETH-SP-G2 is designed for 10/100/1000 Mbps (Gigabit) Ethernet networks and supports both Power-over-Ethernet (PoE) and non-PoE devices. Some sources even indicate compatibility up to 2.5 Gbps, which allows for versatile use.
Do Ubiquiti airMAX devices require additional protection if they already have ESD protection?
Although your Ubiquiti airMAX devices have robust integrated ESD protection, the ETH-SP-G2 provides an *additional* layer of protection. This can be particularly important to meet local building codes and further protect your entire network infrastructure.
What are the grounding requirements for the ETH-SP-G2?
You must properly ground the ETH-SP-G2. This can be done directly to a grounded metal pole or structure using the included screw, or by attaching a grounding wire (not included) to a remote grounding block. Correct grounding is crucial for its function.
