Omnidirectional antenna DeLOCK 12545

The DeLOCK 12545 omni-directional antenna is designed to improve reception across multiple mobile and wireless standards. With a gain of 2 dBi and support for frequency ranges 0.698–0.960 GHz, 1.710–2.170 GHz and 2.300–2.700 GHz, this compact antenna (45 × 45 × 77 mm) is suitable for both indoor and outdoor use. It uses a male SMA connector and a 50 Ω impedance, and is compatible with GSM, UMTS, LTE, ZigBee, DECT, Z‑Wave, NB‑IoT, WLAN, Bluetooth, ISM, TETRA and LoRa.

Advantages

The antenna offers omni-directional reception with a modest 2 dBi gain, delivering consistent coverage in multiple directions. Its broad frequency support covers common cellular, IoT and wireless bands, enabling use with a wide range of devices. The compact housing and standard male SMA connector simplify installation and integration into existing systems.

Suitable for

• Signal reception improvement for cellular (GSM/UMTS/LTE) devices
• Wireless IoT networks (NB‑IoT, LoRa, ZigBee, Z‑Wave)
• WLAN and Bluetooth range extension
• Devices and systems using DECT, ISM or TETRA bands

• Compatibility: GSM, UMTS, LTE, ZigBee, DECT, Z‑Wave, NB‑IoT, WLAN, Bluetooth, ISM, TETRA, LoRa

How to use

Mount the antenna where it has a clear line of sight to the intended coverage area and attach it to a device or cable with a female SMA connector. For outdoor installations ensure the connector and any cable joints are protected from weather exposure. Aligning the antenna vertically typically provides optimal omni-directional coverage; no special tuning is required for the supported frequency bands.

Recommendations

Position the antenna as high as practical and away from large metal objects to reduce signal obstruction. If increased range or directional focus is required, consider a higher-gain or directional antenna appropriate for the target frequency band.
