LWC-868-MM-03 868MHz 4.5dBi SMA Antenna w/ 5m RG58 Cable

This antenna is specifically designed for the 865-868 MHz ISM band, making it ideal for Sub-1GHz wireless communication. Its primary applications include connecting to LoRa or LoRaWAN modules, smart electricity/water/gas meters (AMR/AMI systems), RFID readers, and proprietary wireless sensor nodes. The 5-meter RG58 cable allows for flexible placement, such as mounting the antenna outside an enclosure or away from signal-blocking electronics to improve range and reliability in IoT networks.

The LWC-868-MM-03 assembly is terminated with a standard male SMA plug connector. This is a common RF interface compatible with many wireless modules, development boards, and gateways that feature a female SMA jack. You can connect it directly to devices like LoRa transceiver modules (e.g., SX1276, SX1262), Sub-GHz node PCBs, or IoT gateways. Ensure your device's port is an SMA female jack; for RP-SMA or other connector types, you may require a gender changer or adapter.

For optimal performance, mount the stub antenna vertically to utilize its linear polarization and omnidirectional pattern. Keep the antenna away from large metal objects, walls, or other electronics that can cause signal absorption or reflection. The 5-meter cable provides flexibility to position the antenna in a clear location, such as on a roof, pole, or outside a window. Route the RG58 cable neatly, avoiding sharp bends or kinks that can damage the internal conductor and degrade signal integrity. Ensure the SMA connection is hand-tightened securely to maintain a proper 50-ohm impedance match.
