Antena WiFi 7 omnidirecional para exterior DELOCK 81455 tipo N 4,5–6,6 dBi 32 cm polarização vertical branca

The DELOCK omnidirectional outdoor WiFi 7 antenna (model 81455) is designed to extend wireless coverage for outdoor routers, access points and other network devices. It supports the 2.4–2.5 GHz and 5.15–7.125 GHz frequency ranges used by current WiFi generations including WiFi 7, providing a single vertically polarized radiator with nominal impedance of 50 Ω. The antenna has a compact form factor — approximately 32 cm length and a slim diameter — and comes in a white finish suitable for discreet outdoor installations.

Advantages

The antenna provides omnidirectional signal propagation to cover a wide horizontal area around the installation point while maintaining a fixed vertical polarization to match many outdoor and indoor access points. With a rated gain between 4.5 dBi (minimum) and a maximum of 6.6 dBi, it balances coverage and directivity for general outdoor WiFi extension. The N-type male connector ensures a robust RF connection to compatible external radios and enclosure-mounted network equipment. The lightweight construction supports easy mounting on poles or brackets without heavy structural requirements.

Suitable for

• Extending outdoor wireless coverage for homes, small businesses and public spaces
• Outdoor access points and bridge links requiring omnidirectional coverage
• Integration with routers, gateways or radios that accept an N-type male connector
• Environments using 2.4 GHz, 5 GHz or 6 GHz WiFi bands including WiFi 7-capable equipment

How to use

Mount the antenna on a suitable outdoor pole, mast or bracket ensuring the vertical orientation to maintain the specified polarization. Connect the N-type male connector to the corresponding female connector on your router, access point or radio using an appropriate quality coaxial cable and connectors rated for external use. Position the antenna clear of large metallic obstructions and at an elevated location where it can radiate unobstructed across the target coverage area. Verify the antenna is secured against wind and weather according to the mounting hardware and local installation guidelines.

Recommendations

Use outdoor-rated low-loss coaxial cable and weatherproof the N-type connection with proper sealing materials. For multi-device or high-density deployments consider site planning to avoid co-channel interference and to make best use of WiFi 7 features such as multi-link operation. Confirm that the attached radio or access point supports the frequency ranges you intend to use and adhere to local regulatory limits for transmit power on 6 GHz and other bands.
