Hardware/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 | Link |
| LINX ANT-916-CW-HW-SMA | $14.65 CAD | Link |
| Taoglas TI.09.A.0111 | $17.47 CAD | Link |
Pre-Built
This is a companion node and requires a smartphone. The MeshCore or Meshtastic app connects to the node over Bluetooth (BLE) and is used to send and receive messages on the mesh.
This is the easiest way to get started — buy a companion node, flash your firmware of choice, and join the mesh.
We still recommend you buy one of the antennas listed above, as most manufacturers ship poorly tuned antennas with their devices.
The following pre-built companion nodes are popular and widely available:
| Product | Notes | Link |
|---|---|---|
| LilyGO T-Echo | Compact device designed for Meshtastic/MeshCore with onboard display and GPS.
Good option for those who want something ready to use with minimal setup. |

| SenseCAP T1000-E | A slim card-style tracker device from SeeedStudio.
Portable and simple form factor (also IP65-rated) — easy to carry as a personal node. |

Build Your Own
This is a companion node and requires a smartphone. The MeshCore or Meshtastic app connects to the node over Bluetooth (BLE) and is used to send and receive messages on the mesh.
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 | Link |
| 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.
Standalone Nodes
There are standalone devices such as the T-Deck, but we recommend starting with a companion node instead. Standalone units have quirks and limitations that can make them challenging for beginners.
| Product | Notes | Link |
|---|---|---|
| LilyGO T-Deck Plus | Updated version of the T-Deck with improved specs and refinements.
Designed with Meshtastic/MeshCore in mind for better performance and usability. |
