For reliable and long-range RF performance in the 868 MHz ISM band, it is strongly recommended to use a properly tuned 50Ω external antenna specifically designed for 868 MHz operation. A matched antenna improves transmission efficiency, enhances receiver sensitivity, and ensures stable communication performance.
Using an antenna optimized for the operating frequency helps minimize return loss, low VSWR (Voltage Standing Wave Ratio) and maximizes RF power transfer from the module.
Recommended Antenna: 868 MHz 3 dBi Omni-Directional LoRa SMA Antenna
Key Antenna Characteristics:
- Frequency: 868 MHz ISM Band
- Gain: 3.62 dBi
- Radiation Pattern: Omni-directional
- Connector Type: IPEX MHF1
- Impedance: 50Ω
Important: Always connect the antenna before powering the RF module. Operating the module without a connected antenna may cause RF stage damage and significantly reduce transmission performance.
