Antena omnidireccional DeLOCK 12418 SMA 5 dBi 0.824-1.99 GHz

The DeLOCK 12418 is an omni-directional GSM antenna with a male SMA connector, 50 Ω impedance and a gain of 5 dBi. It covers the frequency ranges 0.824–0.96 GHz and 1.71–1.99 GHz, making it suitable for multiple wireless protocols including GSM bands and compatible with ZigBee (868/915 MHz), DECT, Z-Wave and LoRa (868/915 MHz). The antenna’s compact base (77 × 77 mm) and 319 mm height allow installation indoors or outdoors where extended coverage and uniform signal distribution are required.

Advantages

The omni-directional radiation pattern provides uniform 360° coverage, while the 5 dBi gain improves signal reception and transmission compared with standard whip antennas. The male SMA connector ensures straightforward connection to compatible routers, gateways and modems. Its frequency ranges cover common mobile and IoT bands, enabling use with various devices and networks. The black finish and compact footprint simplify mounting in constrained spaces.

Suitable for

• Extending GSM signal coverage for routers and modems
• IoT gateways using ZigBee, Z-Wave or LoRa in compatible bands
• DECT base stations requiring external antennas
• Indoor or weather-protected outdoor installations where omni-directional coverage is needed

How to use

Attach the male SMA connector to the SMA female port of the router, modem or gateway while the device is powered off or following the manufacturer’s connection instructions. Position the antenna vertically for typical omni-directional coverage and mount it on a stable surface or bracket using the base footprint. For outdoor use, ensure the antenna is placed in a weather-protected or specified outdoor-rated enclosure if the device is not rated for direct exposure.

Recommendations

Place the antenna as high as practical and away from large metal objects or other antennas to reduce interference. Verify device compatibility with SMA male connectors and the supported frequency ranges before installation. For best results in multi-band applications, test placement and orientation to achieve optimal signal strength for your specific network and environment.
