WiFi antenna DELOCK 81468 RP-SMA connector 3.1–3.5 dBi omnidirectional

DELOCK 81468 is an omnidirectional WiFi antenna with an RP‑SMA connector and a specified gain of 3.1–3.5 dBi. Designed for use with routers, access points and network adapters that feature an RP‑SMA port, this antenna helps to improve wireless signal coverage and stability in home and small office environments. The compact form factor and standard connector allow direct replacement or upgrade of existing external antennas without altering device settings.

Advantages

The omnidirectional radiation pattern provides relatively uniform signal distribution around the antenna, which is useful for broad indoor coverage. With a gain in the 3.1–3.5 dBi range, the antenna offers a balance between range extension and pattern stability, reducing dead spots without creating a narrowly focused beam. The RP‑SMA connector ensures compatibility with many consumer routers and adapters that use the same interface. The antenna's simple and lightweight construction supports easy installation and repositioning.

Suitable for

• Improving WiFi coverage in apartments and single rooms
• Small office network setups requiring modest range extension
• Replacing damaged or lost external antennas on routers and USB WiFi adapters
• Temporary or mobile installations where quick connection and repositioning are needed

Key specifications

• Type: omnidirectional WiFi antenna
• Connector: RP‑SMA male
• Gain: 3.1–3.5 dBi
• Frequency range: typical WiFi bands (2.4 / 5 GHz compatibility depends on device implementation)
• Polarization: vertical
• Mounting: direct RP‑SMA connection (no additional mounting hardware included)

How to use

Turn off or disable wireless transmission on the device where you will change the antenna if recommended by the device manual. Unscrew the existing antenna from the RP‑SMA connector and attach the DELOCK 81468 by hand until it is finger‑tight; avoid using tools that could damage the connector. Position the antenna vertically for general omnidirectional coverage or adjust the angle slightly to optimize signal in a particular direction. Power on the device and verify wireless connectivity and signal strength using your operating system tools or the router’s status page. If necessary, try small adjustments to antenna angle or device placement to achieve the best coverage.

Recommendations

For consistent indoor performance, place the antenna clear of large metal objects and away from sources of interference such as microwave ovens or cordless phones. When replacing an antenna on a device with multiple antennas, keep orientations consistent to maintain proper MIMO performance. If longer range or focused coverage is required, consider evaluating higher‑gain or directional antenna options compatible with RP‑SMA connectors.
