915 MHz LoRa Antenna Kit
This kit contains two 915 MHz LoRa antennas rated at 3 dBi gain with SMA male connectors. Each antenna includes a 5.9 inch U.FL to SMA female extension cable for flexible placement. The antennas cover a frequency range of 900 MHz to 930 MHz with 50 ohm impedance and a maximum SWR of 1.8.
Makers Building ESP32 LoRa Nodes
The compact form factor and included U.FL cables suit developers integrating LoRa radio modules onto small boards such as ESP32 OLED LoRa boards. Buyers needing weatherproof outdoor antennas or higher gain for extended rural links should consider other designs.
3 dBi Gain at 915 MHz
The 3 dBi gain figure determines the radiation pattern and link budget for typical indoor or short-range outdoor IoT deployments. Verify that your radio module operates within the 900 MHz to 930 MHz band and uses a U.FL connector before purchasing.

Questions about this item
How do I decide between the two included 915MHz LoRa antennas?
Both antennas are identical 3dBi gain models covering 900-930MHz, so either unit works for the same LoRa IoT application.
What does the 3dBi gain mean when the antenna is mounted on an ESP32 LoRa board?
The 3dBi omnidirectional gain provides focused horizontal coverage for LoRa signals at 915MHz, with a 50-ohm impedance and 1.8 SWR that rises if the antenna is bent 90 degrees.
How does the U.FL to SMA cable affect the connection to my LoRa module?
Each 5.9-inch U.FL MHF1 extension cable converts the module's U.FL port to an SMA female connector, letting you attach the supplied SMA male antennas while positioning them for better reception.
