Omni-directional network antenna DELOCK 81452 RP-SMA, 4.4 dBi, 2.4–7.125 GHz, 169.7 mm

DELOCK 81452 is an omni-directional network antenna with an RP-SMA male connector, designed to provide broad-area wireless coverage across 2.4–7.125 GHz. With a maximum gain of 4.4 dBi and 50 Ω impedance, the antenna supports modern Wi‑Fi bands including 2.4 GHz, 5 GHz and the 6 GHz range used by WiFi 7 (IEEE 802.11be). Its compact dimensions (169.7 mm height, 18.7 mm depth) and lightweight construction (38 g) make it suitable for home, office and small deployment scenarios where enhanced wireless link stability and extended coverage are required.

Advantages

The omni-directional radiation pattern provides even signal distribution in horizontal planes, reducing dead zones in multi-room environments. Support for frequencies up to 7.125 GHz enables compatibility with WiFi 7 features and modern multi-band routers while remaining backward compatible with earlier Wi‑Fi standards. The RP-SMA male connector and standard 50 Ω impedance ensure straightforward integration with a wide range of wireless devices and access points. Physical compactness and light weight simplify installation and repositioning.

Suitable for

• Improving Wi‑Fi coverage in homes and apartments
• Extending wireless range in small offices and meeting rooms
• Enhancing signal reliability for routers, access points and client devices supporting RP-SMA
• Small deployments requiring multi-band support including 2.4 GHz, 5 GHz and 6 GHz

How to use

Attach the antenna to a compatible RP-SMA female socket on a router, access point or wireless device by turning the connector until it is hand-tight. Position the antenna vertically for typical omni-directional coverage; slight tilting can be used to optimize coverage in multi-floor or irregular spaces. Ensure the antenna is mounted clear of large metal objects and sources of interference for best performance. No additional configuration is required at the device level beyond normal wireless settings.

Recommendations

For optimal results, place the antenna at a central, elevated location and avoid obstructions. When deploying in multi-floor environments, experiment with antenna angle and device placement to balance horizontal coverage and vertical reach. Use the antenna with devices that support multi-band operation to take advantage of WiFi 7 capacity and backward compatibility.
