DeLOCK 12711 Omnidirectional Antenna

The DeLOCK 12711 is an omni-directional 5G antenna designed for indoor use that supports multiple 5G frequency bands in the 3.3–5 GHz range. It provides a maximum gain of 4.5 dBi, has 50 Ω impedance and is equipped with an SMA female connector. Its compact dimensions (109 mm depth, 10 mm diameter) and black finish make it suitable for integration with routers, gateways and other wireless devices to improve signal reception and distribution.

Advantages

The omni-directional design offers uniform coverage in all horizontal directions, while the 4.5 dBi gain balances range and compact size. Compatibility with the 3.3–5 GHz frequency band allows use with a variety of 5G deployments. A standard 50 Ω impedance and SMA female connector simplify installation with common networking equipment.

Suitable for

• Indoor 5G routers and gateways
• Signal enhancement for fixed wireless access
• Integration with modems and IoT gateways operating in 3.3–5 GHz
• Small office or home wireless installations
