DeLOCK 89571 Antenna

The DeLOCK 89571 network antenna is a compact dual-band antenna designed for wireless communication in the 2.4 GHz and 5 GHz bands. It provides up to 5 dBi of gain, a 50 Ω impedance and uses an MHF-type connector. With maximum input power rated at 1 W and a slim form factor (7 mm width, 616 mm depth, 1.6 mm height), this antenna is intended for integration into devices or enclosures where space is limited and stable Wi‑Fi performance across IEEE 802.11b/g/n/ac/ax compatible bands is required.

Advantages

The antenna delivers a balanced combination of compact dimensions and moderate gain suitable for extending or stabilizing local wireless links without requiring significant installation space. Its dual-band coverage (2.4–2.483 GHz and 5.15–5.85 GHz) supports both legacy and modern Wi‑Fi channels, while the MHF connector and 50 Ω impedance ensure compatibility with common radio modules and RF front ends. The low maximum power rating and lightweight construction make it safe for low-power embedded systems.

Suitable for (tasks / use cases)

• Embedded Wi‑Fi modules and single-board computers where space is constrained
• Routers, access points and wireless repeaters requiring a slim external antenna
• IoT devices and smart-home equipment operating on 2.4 GHz and 5 GHz bands
• Prototyping and laboratory setups needing a removable MHF antenna

Key specifications

• Antenna gain: 5 dBi (max)
• Frequency bands: 2.4–2.483 GHz and 5.15–5.85 GHz
• Impedance: 50 Ω
• Connector type: MHF
• Maximum input power: 1 W

How to use

Connect the MHF connector to the corresponding antenna port on the wireless module or device, ensuring proper seating and alignment. Position the antenna so it is not tightly bent along its length; maintain gentle curvature if routing is required. Verify that the device is powered off or in a safe state before connecting or disconnecting the antenna. After installation, perform a signal test to confirm expected reception and transmission levels across the 2.4 GHz and 5 GHz bands.

Recommendations

For best performance, avoid placing the antenna directly next to large metal surfaces or dense obstructions. Use the antenna with compatible low-power radio modules and observe the 1 W maximum input power rating. When integrating into enclosures, allow space for the antenna's depth and avoid sharp bends or kinks to preserve RF characteristics.
