Krožna antena DeLOCK 12422

The DeLOCK 12422 omni-directional antenna supports multiple GSM and short-range wireless bands for indoor and outdoor use. It covers frequency ranges of 0.824–0.96 GHz and 1.71–2.17 GHz with a maximum gain of 5 dBi, 50 Ω impedance and an SMA male connector. Compact dimensions (40 × 40 × 340 mm) and a black housing make the antenna suitable for installations where space is limited and stable multi-band reception is required.

Advantages

This antenna provides omni-directional coverage across several mobile and IoT-relevant frequency bands, improving signal reception for devices using ZigBee (868/915 MHz), LoRa (868/915 MHz), DECT, Z-Wave and standard GSM ranges. Its 5 dBi gain and 50 Ω impedance ensure compatibility with typical radio equipment using an SMA male connector while its compact, weather-resistant form factor allows indoor or outdoor mounting.

Suitable for

• Extending GSM coverage for routers, gateways and modems
• Improving reception for ZigBee and Z-Wave smart home hubs
• LoRa gateway and sensor installations in LPWAN deployments
• DECT base stations and other short-range radio equipment
