DeLOCK 88821 Omnidirectional Antenna

The DeLOCK 88821 omni-directional antenna is designed for transmitting and receiving WiFi/WLAN signals complying with IEEE 802.11 a/b/g/n/ac/h standards. It covers the 2.4 GHz and 5 GHz frequency bands (2.4 - 2.4835 GHz and 5.15 - 5.875 GHz), offers an 8 dBi gain and uses vertical polarization with an N-type connector. Its compact dimensions (22.5 mm width and depth, 280 mm height) and light weight make it suitable for indoor and outdoor network deployments where an omnidirectional radiation pattern is required.

Advantages

The antenna provides a balanced 8 dBi gain across common WiFi bands, supporting dual-band operation for legacy and modern IEEE 802.11 standards. The N-type connector ensures a reliable RF connection and the vertical polarization matches typical access point and router orientations. Compact size and lightweight construction simplify mounting and integration into existing network installations.

How to use

Mount the DeLOCK 88821 antenna in a location that provides clear signal propagation for the intended coverage area. Connect the N-type connector to the compatible port on your access point, router or wireless device, ensuring a secure mechanical fit. Orient the antenna vertically to match its polarization and the polarization of the communicating equipment. Verify proper attachment and, if installed outdoors, use appropriate weatherproofing for the connector and mounting hardware.

Recommendations

For optimal performance, place the antenna at a central, elevated position relative to the coverage area and avoid nearby large metallic objects or obstructions. When using outdoors, secure the antenna and protect the N-type connection against moisture. Confirm compatibility with your device’s connector and supported frequency ranges before installation.
