DeLOCK 89454 Network Antenna

The DeLOCK 89454 Network Antenna is a compact WLAN twin antenna with MHF IV connectors and two separate radiating elements sharing a common ground. It supports dual-band operation for 2.4–2.5 GHz and 5.1–5.875 GHz, offers a maximum gain of 5 dBi and is compatible with IEEE 802.11a/b/n/ac/h standards. The antenna includes a 0.15 m coax cable and has compact dimensions (61.6 × 7 × 1.6 mm) for easy integration into devices and enclosures.

Advantages

The twin-antenna design provides improved spatial diversity and better signal reliability compared with a single element. Compact form factor and an MHF IV connector allow internal installation in consumer or industrial devices. Dual-band frequency support and a 5 dBi gain help enhance wireless coverage for both 2.4 GHz and 5 GHz networks while maintaining compatibility with common IEEE Wi‑Fi standards.

Suitable for

• Embedded Wi‑Fi modules and wireless routers with MHF IV connectors
• IoT devices, gateways and access points requiring internal antennas
• Upgrading or replacing internal antennas in laptops, industrial equipment or bespoke enclosures

How to use

Connect each MHF IV connector to the corresponding RF socket on your device’s wireless module or adapter. Position the antenna elements inside the device housing to avoid metallic obstructions that can degrade performance. Secure cables to prevent strain on the connector and route the 0.15 m coax cable so it does not interfere with internal components. After installation, test signal levels and adjust placement if required to optimise reception.

Recommendations

For best performance, place the antenna away from large metal surfaces and strong RF sources. If installing into an enclosure, allow a small clearance around the antenna elements and verify compatibility with your module’s MHF IV connector type before fitting.
