Lightning Arrestor 2 for LoRaWAN®

What is Lightning Arrestor 2 for LoRaWAN?

For outdoor LoRa deployments, lightning protection is critical. The Lightning Arrestor 2 (Model: LA-GT1000 SN1-1) is a next-generation RF surge protector for IoT and outdoor RF systems, engineered to safeguard LoRa gateways and sensitive transceivers from lightning-induced surge events. Designed for 50Ω RF systems operating in the 800–960 MHz range, it provides precision protection without compromising signal performance.

Why You Need Lightning Protection for Outdoor Gateways for LoRaWAN

Protecting outdoor communication systems with proper LoRaWAN lightning protection safeguards uptime, extends equipment lifespan, and avoids costly service interruptions.

Why it's useful:

• Two-stage surge suppression: Unlike earlier models, Lightning Arrestor 2 integrates a two-stage protection circuit. This significantly reduces residual voltage to ≤15V, perfect for sensitive electronics.
• LoRa-optimized performance: Targeting the 800–960 MHz band ensures optimal integration with LoRaWAN® gateways and similar sub-GHz RF systems.
• Industrial-grade durability: Certified IP67, this device is dust-tight and water-resistant. It’s built with high-conductivity copper, PTFE insulation, and ternary alloy inner connectors.

Two-Stage Surge Suppression: How It Works

Lightning Arrestor 2 uses a two-stage surge suppression architecture to protect sensitive LoRaWAN and sub-GHz RF equipment from lightning-induced transients. This layered approach is designed to handle both high-energy surge events and the low residual voltages that can still damage modern RF front ends.

Stage 1: Primary Energy Diversion

The first stage acts as the main defense against lightning surges and induced overvoltage spikes. When a surge enters the RF line, this stage rapidly diverts the majority of the energy away from the signal path and into the grounding system. By absorbing and shunting high-current impulses (up to 10kA, 8/20 µs), it prevents destructive energy from reaching downstream electronics.

Stage 2: Precision Voltage Clamping

After the bulk energy is discharged, the second stage handles what remains, functioning as a low residual voltage lightning arrestor for sensitive RF front ends. This stage clamps residual voltage to a very low level, ≤ 15V, which is critical for protecting sensitive RF transceivers, LNAs, and gateway input stages. Single-stage protectors often leave hundreds or even thousands of volts behind; this second layer ensures that even small, fast transients are safely suppressed.

Why Two Stages Matter for LoRa Deployments

gateways for LoRaWAN and IoT radios operate with low signal levels and highly sensitive input circuits. Broad, single-stage lightning protectors may survive a strike but still allow damaging voltage spikes to pass through. By combining high-energy diversion with fine voltage control, the two-stage design delivers both robust surge handling and precise protection, without degrading RF performance across the 800–960 MHz band.

The result is a lightning protector specifically engineered for outdoor LoRa installations, maintaining signal integrity during normal operation while providing industrial-grade protection during extreme electrical events.

Why choose Lightning Arrestor 2 for LoRaWAN networks?

Lightning Arrestor 2 is engineered specifically for outdoor LoRaWAN deployments where low residual voltage protection is essential for sensitive RF front ends. Unlike broadband arrestors that clamp at 60–300+ volts, the two-stage design of Lightning Arrestor 2 reduces surge energy to ≤15 V, making it ideal for SX130x/SX126x-based LoRa gateways. With IP67 weatherproofing, low insertion loss, and a LoRa-tuned 800–960 MHz band, it is one of the most reliable surge protectors for remote IoT deployments, agriculture, utilities, and smart industrial monitoring.
