Antena omnidirecional DeLOCK 12427

The DeLOCK 12427 is an omni-directional LTE antenna with an SMA male connector, designed for indoor and outdoor use. It covers frequency ranges of 700–960 MHz and 1710–2690 MHz, offers 5 dBi gain and a 50 Ω impedance. The antenna includes a magnetic base and a 3 m RG-174 coaxial cable with a diameter of approximately 2.7 mm. Its compact dimensions (approx. 337 mm length including base and 40 mm magnetic base diameter) make it suitable for various installations where reliable multi-band reception and transmission are required.

Advantages

The antenna supports multiple protocols and bands including GSM, UMTS, Bluetooth, WLAN 2.4 GHz, ZigBee, DECT, Z-Wave and LoRa (868/915 MHz), enabling broad compatibility with communication devices. It provides a steady 5 dBi gain with vertical polarisation, low VSWR (≤2.0) and can handle up to 50 W transmission power. The included 3 m RG-174 cable simplifies placement while the magnetic base allows stable mounting on metal surfaces.

Suitable for

• Extending cellular LTE/GSM/UMTS reception for routers and modems
• Wireless IoT networks using ZigBee, Z-Wave or LoRa
• Bluetooth and 2.4 GHz WLAN signal improvement
• DECT base stations and other short-range wireless devices

How to use

Connect the SMA plug to a device with a free SMA jack such as an LTE router, modem or other wireless equipment. Place the antenna on a suitable metal surface using the magnetic base for improved stability and grounding; route the 3 m RG-174 cable to reach the device. Align the antenna vertically for correct polarisation and ensure the selected frequency bands are supported by the connected device.

Recommendations

Install the antenna in a location with minimal obstructions and elevated position where possible. Avoid sharp bends in the RG-174 cable and maintain the magnetic base on a clean, flat metal surface to maximise performance. Verify compatibility of frequency bands before installation.
