DeLOCK 12409 Omnidirectional Antenna

The DeLOCK 12409 is an omni-directional antenna designed to improve reception across multiple LTE and Wi‑Fi frequency bands. With a maximum gain of 4 dBi and a compact form factor (39.8 × 156.2 × 13.5 mm), it connects via an RP‑SMA connector and supports a wide range of mobile and wireless standards including LTE, Bluetooth, UMTS, GSM, WLAN (dual band) and ZigBee.

Advantages

This antenna offers omni-directional coverage with a 4 dBi gain suitable for indoor installation. It covers multiple frequency ranges (0.698–0.791 / 0.824–0.96 / 1.71–2.17 / 2.4–2.5 / 5.15–5.875 GHz), provides a compact footprint for flexible placement, and uses an RP‑SMA connector for straightforward integration. Its specified VSWR range (2.5:1–5.0:1) indicates design characteristics for efficient signal transmission across supported bands.

Suitable for

• Improving indoor LTE signal reception
• Enhancing Wi‑Fi coverage on 2.4 GHz and 5 GHz bands
• Connecting devices using Bluetooth, UMTS or GSM frequencies
• Supporting ZigBee and other low‑power wireless systems
