DeLOCK 88899 Omnidirectional Antenna

The DeLOCK 88899 is an omni-directional Wireless LAN antenna designed to connect to devices with an RP-SMA interface to send and receive Wi‑Fi signals. It covers the 2.4–2.4835 GHz and 5.15–5.875 GHz frequency bands, supports IEEE 802.11a/b/g/n/ac/h standards and has a maximum gain of 7 dBi. The antenna is finished in black and has compact dimensions (18.4 mm × 18.4 mm × 231 mm) suitable for improving wireless coverage in homes, offices and public spaces.

Advantages

The omni-directional design provides 360° signal dispersion for more uniform coverage around the installation point. A 7 dBi gain boosts signal strength compared with typical low‑gain antennas, helping to extend range and improve link stability. The RP‑SMA connector ensures compatibility with many routers, access points and wireless adapters that use this interface. Compact size and neutral black colour allow discreet mounting in a variety of indoor environments.

Suitable for

• Extending Wi‑Fi coverage in homes and apartments
• Improving wireless signal in small offices and meeting rooms
• Use with routers, access points and USB wireless adapters featuring an RP‑SMA interface
• Enhancing connectivity in public indoor areas such as cafés or lobbies

How to use

Attach the DeLOCK 88899 to the RP‑SMA connector on your router, access point or wireless adapter by screwing the connector clockwise until secure. Position the antenna vertically for typical omni‑directional coverage; adjust orientation slightly if needed to optimise signal in the target area. After connection, verify the device recognises the antenna and test signal strength at desired locations. If replacing an existing antenna, power off the device before detaching and attaching connectors when recommended by the device manufacturer.

Recommendations

Install the antenna in a clear, elevated location away from large metal objects and electronic sources of interference for best performance. Ensure the RP‑SMA connector type matches your device before purchase.
