Companion Nodes
Antenna Recommendation
Almost every LoRa device ships with a very basic factory antenna that performs poorly. The Ottawa mesh community has tested many replacements, and the following antenna is highly recommended as a reliable upgrade:
| Product | Cost (CAD) | Link |
|---|---|---|
| Gizont 167CM 915MHz SMA M | $10.53 CAD | www.aliexpress.com/item/1005004607615001.html |
Build Your Own
For hobbyists who like to source parts and assemble their own node, here’s an example Ottawa-friendly build (antenna not included here, see above recommendation):
| Item | Product Name | Cost (CAD) | Link |
|---|---|---|---|
| LoRa Board | Heltek T114 (Bundle: Screen Case) | $48.18 CAD | www.aliexpress.com/item/1005007916299029.html |
| Battery | Makerfocus 3.7V 3000mAh Lipo | $10.00 CAD | Link |
Approximate total cost (excluding antenna): $58.18 CAD
Take a peek at Alley Cat’s models — they’re excellent 3D-printable cases for custom companion node builds.
