Alfa Dual-Band Outdoor Omni Wi‑Fi Antenna 7/9 dBi N‑Male

The Alfa AOA-2458-79AM is a dual-band outdoor omnidirectional antenna covering the 2400–2500 MHz and 5150–5875 MHz frequency ranges. It provides 7 dBi gain in the 2.4 GHz band and 9 dBi gain in the 5 GHz band, supporting wireless equipment that operates across both frequency ranges. The antenna uses linear vertical polarization and has a maximum VSWR of 2.0:1. Its omnidirectional radiation pattern distributes coverage around the antenna in the horizontal plane rather than concentrating it in a single direction, which suits installations where communication is required around the mounting point. The antenna has a 50-ohm impedance and connects through an N Male connector for direct attachment to compatible equipment.

With a length of 322 mm, the antenna uses a slim direct-mount format that keeps the installation close to the connected device without requiring a separate antenna cable in this configuration. The supported operating temperature range extends from -40 °C to +85 °C, allowing deployment across a wide range of environmental conditions. Operating humidity is specified from 5% to 95% non-condensing. The antenna is rated for 2 W power handling, matching its role as a compact external antenna for compatible wireless equipment. Its combination of dual-band coverage, different gain levels for the two supported bands, N Male connection, vertical polarization, and direct mounting provides a straightforward antenna option for installations that require omnidirectional coverage from a device-mounted antenna.
