Alfa 2.4/5GHz Outdoor Wi‑Fi Antenna 7/9dBi N‑Female

The ALFA Network AOA-2458-79AF is an omnidirectional dual-band antenna designed for operation in the 2.4 GHz and 5 GHz frequency bands. Its omnidirectional radiation pattern provides coverage around the antenna rather than concentrating the signal in a single horizontal direction. The antenna operates across 2400–2500 MHz and 5150–5875 MHz, with a gain of 7 dBi in the lower frequency band and 9 dBi in the higher band. This configuration enables a single antenna to operate within both specified frequency ranges, while the different gain values should be considered when evaluating its performance in each band. The antenna also uses linear vertical polarization, an important characteristic when selecting equipment with a corresponding polarization. Its dual-band operation and omnidirectional design make it relevant for configurations where signals must be transmitted or received in multiple horizontal directions without relying on a directional antenna.

The AOA-2458-79AF features an N Female connector for connection to equipment or coaxial cables fitted with a corresponding N Male connector. Its 50-ohm impedance should be taken into account when choosing compatible RF equipment and connecting components. With a length of 317 mm, the antenna has a defined physical size that can be considered when planning installation space and connection placement. The specified operating temperature range extends from −40 °C to +85 °C, allowing its environmental requirements to be evaluated alongside those of the connected equipment. Together, its omnidirectional coverage, dual-band frequency operation, vertical polarization and N Female connection make the AOA-2458-79AF a practical antenna option for installations requiring these documented characteristics.
