Building a Go-Bag Node Kit

Building a Go-Bag Node Kit

A go-bag node kit is a self-contained, portable LoRa mesh capability you can deploy immediately in an emergency without depending on fixed infrastructure. The goal is a kit you can grab and go, with everything needed to establish mesh communications from any location.

Core Components

ComponentRecommended OptionNotes
LoRa Node Heltec V3 or T-Deck Plus T-Deck Plus has a built-in keyboard and screen for standalone operation without a phone; Heltec V3 requires companion app on phone
External Antenna Fiberglass omni, 3 - 5 dBi Significant range improvement over stock PCB antenna; choose one with SMA connector matching your node
Power Bank 10,000+ mAh A 10,000 mAh bank can run a Heltec V3 for days; larger capacity preferred for extended deployments
Short Coax Jumper U.FL to SMA, 15 - 30 cm Connects the node's U.FL port to an external SMA antenna; match connector types to your specific hardware
USB-C Cable (spare) Short, braided For charging/data; carry at least one spare

Optional Additions

  • Magnetic antenna mount: For vehicle deployment - place antenna on roof for dramatic range improvement
  • Waterproof case: Pelican 1150 or similar; protect electronics in wet conditions
  • Small tripod or mast: Elevate antenna 2 - 3 meters above ground when vehicle deployment isn't available
  • Solar panel: 10 - 20W panel + small charge controller for indefinite field deployment
  • Printed QR code: Link to your local network's channel settings for quick onboarding of others

Kit Preparation

Configure the device before an emergency. A go-bag kit with unconfigured or default-password hardware is useless under stress. Before packing the kit:

  1. Flash and configure the node with the correct channel/preset for your local network
  2. Change all default passwords on any room server firmware
  3. Test connectivity with known nodes in your area
  4. Label the device with your callsign or contact info
  5. Export and store a config backup
