Lightning Arrestor 2 (Model: LAGT1000 SN11) is an RF surge protection device designed specifically for outdoor LoRa deployments where lightning protection is essential. It safeguards LoRa gateways and sensitive RF transceivers from lightninginduced surge events, ensuring system reliability in outdoor IoT environments.
Engineered for 50ohm RF systems operating within the 800960 MHz frequency range, the device delivers precise surge protection while maintaining signal integrity. It is fully compatible with SX130xbased and SX126xbased LoRaWAN gateways commonly deployed in outdoor IoT networks.
Protecting outdoor communication systems with proper LoRaWAN lightning protection safeguards uptime, extends equipment lifespan, and avoids costly service interruptions.
Why it’s useful:
Lightning Arrestor 2 uses atwo-stage surge suppression architectureto 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.
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 s), it prevents destructive energy from reaching downstream electronics.
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.
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 bothrobust surge handling and precise protection, without degrading RF performance across the 800960 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.
Lightning Arrestor 2 for LoRaWAN is designed for:
It is best suited for deployments where gateway reliability, long-term durability, and signal integrity are critical.
Lightning Arrestor 2 is engineered as an outdoor RF surge suppressor for harsh environmental conditions. Its IP67-rated housing is dust-tight and water-resistant, protecting internal surge components from rain, moisture, and debris. Built with corrosion-resistant metals, high-conductivity copper, and PTFE insulation, it delivers reliable long-term protection for LoRaWAN and outdoor IoT installations with minimal maintenance.
Tuned for the 800960 MHz LoRa band, Lightning Arrestor 2 deliverslow VSWR ( 1.25)andminimal insertion loss ( 0.3 dB), reducing reflections and signal attenuation. This ensures reliable long-range communication without compromising RF performance.
