Alfa 2.4/5GHz Outdoor Dual-Band Wi‑Fi Antenna 4/6dBi N‑Male

The ALFA Network AOA-2458-46ACM is a dual-band outdoor omnidirectional antenna designed to operate across the 2400–2483 MHz and 5150–5875 MHz frequency ranges. It provides 4 dBi gain in the 2.4 GHz band and 6 dBi gain in the 5 GHz band, supporting wireless equipment that uses either supported frequency range through a single antenna. Its omnidirectional radiation pattern distributes radio coverage around the antenna rather than concentrating it in one direction, making the antenna suitable for installations where signals need to be transmitted and received from multiple directions. A 50 Ω impedance and N Male connector define its RF interface, while the specified maximum VSWR of 2.0:1 indicates the antenna’s matching performance across its operating ranges.

The antenna has a compact cylindrical form measuring approximately 22 mm in diameter and 180 mm in length, with a weight of 70 g. These dimensions make it practical for direct connection to compatible outdoor wireless devices without adding a large external antenna assembly. Its specified operating temperature range extends from −40 °C to 85 °C, allowing deployment across environments exposed to substantial temperature variation. The antenna is also specified for humidity up to 95% at 25 °C. Together with its dual-band frequency coverage, moderate gain levels, and N Male connection, these mechanical and environmental characteristics provide the information needed to assess compatibility with equipment, available mounting space, and expected installation conditions.
