Antennas, LoRa, and RF
Selecting Components
After selecting your configuration, order all required components, including:
- Battery (appropriate chemistry and capacity)
- Antenna with the correct connector
- Power switch
- Mounting hardware (screws, standoffs, enclosure)
- Optional accessories, such as sensors, GPS modules, or displays
Antenna and RF Connectors
⚠️ Important: Verify your antenna cable and connector type before ordering.
Many LoRa radios use U.FL → SMA pigtails. SMA and RP-SMA (reverse polarity) are NOT compatible, even though they appear similar.
Another common RF connector on compact boards is MHF4, which is smaller and not interchangeable with U.FL.
