DeLOCK 86151 WLAN Antenna, 3 dBi, Internal

The DeLOCK 86151 wireless LAN antenna is a compact external antenna designed for devices with an I-PEX connector. It operates in the 2.4–2.5 GHz frequency band, provides a maximum gain of 3 dBi and has an impedance of 50 Ω. The antenna comes with a 0.2 m cable and measures 25 × 6 × 5 mm, making it suitable for improving signal reception in small wireless setups.

Advantages

The antenna offers a moderate 3 dBi gain for enhanced reception on 2.4 GHz Wi‑Fi networks while maintaining a small form factor and lightweight design. Compatibility with I-PEX interfaces and a short 0.2 m cable supports easy installation on devices with limited internal space. Its 50 Ω impedance matches common WLAN hardware requirements.

Suitable for

• Small wireless routers and access points with I-PEX connectors
• Embedded Wi‑Fi modules in IoT devices and single-board computers
• Upgrading reception on laptops, mini PCs or network cards using I-PEX

How to use

Connect the antenna to the device's I-PEX connector following the device manufacturer’s instructions. Position the antenna to reduce obstructions between the device and the wireless access point to improve signal strength. Ensure the connector is seated securely and route the 0.2 m cable without sharp bends. Power on the device and verify improved reception in the network settings or with diagnostic tools.

Recommendations

For best results, place the device and antenna away from large metal objects and sources of interference (microwaves, cordless phones). If the antenna is used in an enclosed case, allow some clearance for optimal radiation; check compatibility with your hardware manual before installation.
