LoRa SPD Datasheet
Overview
Description
The LoRa SPD, also known as the LA-GT1000 SN1-1 Lightning Arrestor 2, is an outdoor RF surge protection device installed between the antenna and the LoRa gateway to prevent damage from lightning-induced surges, transient voltages, and overcurrent events. It features a two-stage protection circuit that ensures fast response and stable signal transmission with low insertion loss and 50 Ω impedance across the 800 MHz~960 MHz range.
Constructed from high-conductivity copper and enclosed in an IP67-rated housing, the LoRa SPD provides reliable and durable performance in harsh outdoor environments.
