Κεραία DeLOCK 89457

The DeLOCK 89457 WLAN twin antenna is a compact dual-antenna module designed for devices with MHF/U.FL connectors. It provides two separate antenna elements with a common ground, supports IEEE 802.11a/b/g/n/ac/h standards and operates in the 2.4–2.5 GHz and 5.1–5.875 GHz frequency bands. The antenna offers up to 5 dBi gain and comes with a 0.5 m cable; its small dimensions make it suitable for integration into space-limited equipment.

Advantages

The twin-antenna design delivers improved reception and transmission diversity compared with a single element antenna. A maximum gain of 5 dBi balances range and compactness. The MHF/U.FL connector and 0.5 m cable simplify connection to Wi‑Fi modules and mini PCIe or M.2 wireless cards. Its small size and black colour allow discreet installation inside various devices.

Suitable for

• Integration in routers, access points and embedded Wi‑Fi modules with MHF/U.FL connectors
• Client devices and mini PCIe / M.2 wireless cards requiring external twin antennas
• Industrial or compact electronic devices where space is limited

How to use

Attach the MHF/U.FL connector to the corresponding socket on your wireless card or module, taking care to align the connector correctly before applying gentle pressure. Route the 0.5 m cable and position the antenna elements inside the device to minimize obstructions and metallic shielding that can degrade signal. Ensure both antenna elements share the common ground connection provided by the product.

Recommendations

For optimal performance, place the antenna elements with clear line-of-sight to the coverage area and avoid close proximity to large metal surfaces or cables. Confirm compatibility with your device's connector type (MHF/U.FL) before installation. Observe ESD precautions when handling connectors and internal circuitry.
