Key specifications

How to use

Connect the SMA plug of the antenna to the SMA socket of your ZigBee device. Position the antenna vertically for optimal linear polarisation and best performance at 868 MHz. Ensure the connector is finger-tight and not overtightened to avoid damage. Adjust placement to reduce obstructions and interference from nearby metal objects or large electronic devices.

Recommendations

For improved reception, place the antenna away from large metal surfaces and at a higher position when possible. If you replace an existing antenna, compare gain and VSWR specifications to ensure compatibility with your device.
