Παντοκατευθυντική κεραία DeLOCK 12722

The DeLOCK 12722 is an omni-directional antenna designed for use in the 0.868 GHz (868 MHz) band. It provides a maximum gain of 4.5 dBi, has a 50 Ω impedance and an SMA female connector. With compact dimensions (33 x 33 x 210 mm) and a black finish, the antenna is suitable for improving reception both indoors and outdoors for compatible LPWAN and other radio devices operating on the 868 MHz band.

Advantages

The omni-directional design offers uniform signal coverage around the antenna, while the 4.5 dBi gain improves receive and transmit range without requiring complex alignment. The SMA female connector ensures compatibility with many gateways, routers and modules. Its compact size and weather-tolerant appearance make it convenient for installations where space is limited.

Suitable for

• LPWAN gateways and end devices operating at 868 MHz
• IoT sensors and trackers requiring improved radio range
• Indoor and outdoor installations where multi-directional coverage is needed

Key specifications

• Frequency band: 0.868 GHz (868 MHz)
• Gain (max): 4.5 dBi
• Impedance: 50 Ω
• Connector: SMA female
• Colour: Black
• Dimensions (W × D × H): 33 × 33 × 210 mm

How to use

Connect the antenna to the SMA male connector on your compatible device (gateway, router, radio module). Position the antenna vertically to achieve optimal omni-directional coverage. For outdoor use, mount the antenna securely using appropriate brackets or holders and ensure the connector is protected from direct water ingress if the installation is not fully weatherproof.

Recommendations

Verify device compatibility with a 50 Ω SMA female antenna and the 868 MHz frequency band before installation. Avoid placing large metallic objects immediately adjacent to the antenna and allow a clear surrounding area for best performance.
