LWC-868-MM-03 868MHz 4dBi SMA Antenna w/ 3m RG58 Cable

The LWC-868-MM-03 antenna is specifically tuned for the 865 to 868 MHz frequency band. This makes it ideal for European ISM band applications, including LoRaWAN, Sigfox, and other proprietary Sub-GHz wireless protocols that operate within this licensed-exempt spectrum. Ensure your transceiver module is configured for this band for optimal performance.

Yes, this antenna is directly compatible. The integrated cable is terminated with an SMA plug (male connector), which is designed to screw into a standard SMA female jack found on most RF modules and gateways. Ensure a secure connection to maintain the 50-ohm impedance match and prevent signal loss or interference at the connector interface.

The 3-meter RG58 cable provides installation flexibility, allowing you to place the antenna away from electronic noise or obstructions while keeping the radio module in an enclosure. RG58 offers a good balance between flexibility and low attenuation per meter at 868MHz. Avoid sharply bending or crushing the cable, as this can degrade the impedance match and increase signal loss.

For optimal omnidirectional coverage, mount the antenna vertically. Its linear polarization and 360-degree horizontal beamwidth are designed for vertical orientation. Ensure the radiating element is clear of large metal objects or dense walls. The 3-meter cable allows routing to a suitable location, such as a mast, wall, or enclosure exterior, to maximize line-of-sight range.

While the product description mentions a powder-coated aluminum housing, which offers some environmental protection, specific IP ratings are not provided. For permanent outdoor deployment, consider adding a protective radome or installing it in a location shielded from direct rainfall. The RG58 cable jacket is typically PVC, which is suitable for general outdoor use but may degrade over years in direct sunlight.
