Page 3: Outdoor Surge Protection System
1. Outdoor Surge Protection System 1.1 Antenna Grounding RAKwireless recommends a lightning arrestor to be installed on all the antenna N- Type terminals (LoRa, LTE, Wi-Fi and GPS). It is recommended to use a 10 AWG or better grounding wire to connect the arrestor to the tower mounted LoRa antenna. -
Page 4: Indoor Surge Protection System
Please refer to the images in the diagram below for the Outdoor and Indoor portion of the surge protection system. Should you fail to adhere to the recommendations in this document RAKwireless carries no responsibility for any damage your equipment incurs due to lightning strike! Note: Make sure to provide all the grounding points for the antennas (GPS arrester is of a different class as seen below), gateway housing, and Ethernet SPD. -
