Description

The LWC-868-MM-03 is a complete RF antenna cable assembly engineered for sub-1GHz wireless communication systems. It integrates a compact, 4 dBi gain stub antenna directly onto a 1-meter RG58 coaxial cable, providing a streamlined solution for connecting 868 MHz transceivers to an external radiating element. The assembly is characterized by its 50-ohm impedance matching, ensuring minimal signal loss and reflection with a VSWR under 2.0 across the target band.

Constructed for durability and consistent performance, the antenna’s linear polarization and omnidirectional horizontal pattern make it suitable for a wide range of fixed and mobile IoT deployments. The included SMA male connector offers a standard, secure interface for modules and gateways, simplifying integration into prototypes and final products requiring reliable RF links in the European 868 MHz ISM band.

Key Features

  • Band-Optimized Stub Antenna: Specifically designed for the 865–868 MHz ISM band, ensuring maximum radiation efficiency for LoRaWAN, Sigfox, and proprietary protocols.
  • Integrated Cable Assembly: Pre-attached 1-meter RG58 cable eliminates the need for separate cable sourcing and connector soldering, reducing assembly time and potential points of failure.
  • High-Power Handling: Capable of handling up to 10 watts of RF input power, making it suitable for both low-power sensor nodes and higher-power base station or gateway applications.
  • Low VSWR Design: Voltage Standing Wave Ratio (VSWR) is maintained below 2.0, indicating excellent impedance matching and efficient power transfer from the transmitter to the antenna.
  • Omnidirectional Radiation Pattern: Provides 360-degree coverage in the horizontal plane with a focused vertical beamwidth (30°–40°), offering a good balance between range and signal stability.
  • Standard SMA Interface: SMA male plug connector ensures broad compatibility with a vast array of wireless modules, development boards, and industrial gateways.

Applications

  • Sub-GHz IoT Sensor Networks: Deploy with LoRa, LoRaWAN, or Sigfox end-nodes for environmental monitoring, smart agriculture, and asset tracking.
  • Smart Metering Infrastructure: Provide a reliable RF connection for wireless AMI (Advanced Metering Infrastructure) and utility meter communication hubs.
  • RFID Reader Systems: Enhance the read range and reliability of UHF RFID readers and gateways operating in the 868 MHz band.
  • Industrial Wireless Telemetry: Connect to PLCs, RTUs, or wireless modems for remote data acquisition and control in SCADA and IIoT systems.
  • Wireless Alarm & Security Systems: Serve as the external antenna for long-range wireless alarms, sensors, and perimeter detection systems.

Frequently Asked Questions

What is the exact frequency range this antenna cable assembly is designed for?

The LWC-868-MM-03 assembly is specifically tuned for the 865 to 868 MHz Industrial, Scientific, and Medical (ISM) band. This frequency range is commonly used across Europe for LoRaWAN, Sigfox, and various proprietary sub-1GHz wireless protocols, ensuring optimal impedance matching and radiation efficiency for devices operating within this narrow spectrum.

Can I use this SMA antenna cable with my LoRaWAN gateway or node?

Yes, this antenna is an ideal match for LoRaWAN equipment operating in the 868 MHz EU band. Its 50-ohm impedance and SMA male connector are standard for most LoRa modules and gateways. Ensure your device has a female SMA port. The 4 dBi gain and omnidirectional pattern provide a balanced improvement in link range without excessively narrowing the beam, suitable for both fixed gateways and mobile sensor nodes.

What are the installation considerations for this stub antenna?

For best performance, mount the antenna stub vertically to utilize its linear polarization and defined vertical beamwidth. Ensure the SMA connection is hand-tightened securely to maintain a consistent 50-ohm path and prevent signal leakage. Avoid placing the antenna near large metal objects or enclosures that could detune it or block its 360-degree horizontal coverage. The 1-meter RG58 cable offers flexibility for routing away from interference sources.
