Mindenirányú antenna DeLOCK 89769

The DeLOCK Omni-directional antenna 89769 enables use of the 868 MHz band both indoors and outdoors. It features a compact 135 mm height, SMA female connector and 50 Ω impedance, and is intended to improve reception and transmission performance for devices operating in the 0.86–0.87 GHz range.

Advantages

This antenna provides an omnidirectional radiation pattern with a maximum gain of 3 dBi, making it suitable for general coverage around the installation point. Its SMA female connector and 50 Ω impedance ensure compatibility with a wide range of radio modules and gateways. The compact black housing is suitable for mounting in confined spaces while maintaining stable performance across the specified frequency band.

Suitable for

• IoT gateways and sensors using the 868 MHz band
• Wireless alarm systems and remote controls
• Short-range telemetry and data links
• Indoor and outdoor installations where omnidirectional coverage is required

Key specifications

• Frequency band: 0.86 - 0.87 GHz
• Antenna gain (max): 3 dBi
• Impedance: 50 Ω
• Connector: SMA female
• Height: 135 mm
• Colour: Black

How to use

Attach the antenna to a compatible SMA male connector on your device or extension pigtail. Position the antenna vertically for typical omnidirectional coverage. For outdoor use, mount it in a weather-protected location or use appropriate sealing around the connector. Verify that the connected device is configured for the 0.86–0.87 GHz frequency range before operation.

Recommendations

To achieve optimal performance, keep the antenna clear of large metal objects and maintain a short, low-loss cable between the antenna and radio equipment. Ensure compliance with local regulations regarding transmission power and permitted frequency bands when using the 868 MHz band.
