ALFA Dual-Band Outdoor Omni Wi‑Fi Antenna 5/9 dBi, N-Female

The ALFA AOA-2458-59TFL is a dual-band outdoor omnidirectional antenna covering the 2400–2483 MHz and 5150–5850 MHz frequency ranges. It provides 5 dBi gain at 2.4 GHz and 9 dBi gain at 5 GHz, combining support for both bands in a single antenna. The omnidirectional radiation pattern distributes radio coverage around the antenna rather than concentrating it in one direction, making the design suitable where communication is required across the surrounding area. A VSWR of no more than 2.0 defines the specified matching performance, while the 50-ohm impedance matches the stated electrical characteristics of the antenna. Connection to compatible equipment is provided through an N Female connector.

The antenna uses a fiberglass radome and has an overall length of 260 mm, giving it a slim form for outdoor installation. Its dual-band construction means one antenna can operate across both supported frequency ranges without requiring separate antennas for 2.4 GHz and 5 GHz use. The different gain values reflect its stated performance in each band: 5 dBi at 2.4 GHz and 9 dBi at 5 GHz. Together with omnidirectional radiation, this supports installations that need surrounding coverage while retaining the specified gain for each operating band. The combination of N Female connectivity, 50-ohm impedance, fiberglass construction, and dual-band operation makes the AOA-2458-59TFL a practical external antenna for compatible wireless equipment operating within the listed frequency ranges.
