Antena omnidireccional DeLOCK NB-IoT 3 dBi

The DeLOCK NB-IoT Omni-directional antenna provides indoor use of the 900 MHz (0.9 GHz) band and is built for NB‑IoT connectivity. It has a compact cylindrical form factor (135 mm height, 10 mm diameter), a black finish and an SMA female connector for easy installation. The antenna features 3 dBi gain, 50 Ω impedance and is supplied in box model 89770 (EAN 4043619897704).

Advantages

This omni‑directional antenna offers uniform signal reception and transmission in all horizontal directions, a small footprint for installation in confined spaces, and a standard SMA female connector for compatibility with many NB‑IoT gateways and modems. The 3 dBi gain and 50 Ω impedance support stable indoor NB‑IoT links in the 900 MHz band.

Key specifications

How to use

Connect the antenna to the SMA male connector on the NB‑IoT device or gateway and position it vertically to achieve omni‑directional coverage. Place the antenna in a central indoor location, away from large metallic obstructions, to maximize signal distribution. No additional setup is required beyond mechanical mounting and electrical connection.

Recommendations

For best indoor performance, mount the antenna at a moderate height and keep clear of metal cabinets or heavy electronic equipment. If coverage is insufficient, try repositioning the antenna or using multiple antennas on separate devices to improve local reception.
