Alfa 2.4/5GHz 5/9dBi Omni Antenna – Dual-Band RP-SMA Male

The ALFA Network AOA-2458-59-TSL 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 2400–2483 MHz and 5150–5875 MHz, with a gain of 5 dBi in the lower band and 8.4 dBi in the higher band. This dual-band configuration allows a single antenna to operate within both specified frequency ranges, while the different gain values are important when evaluating its characteristics for each band. The omnidirectional design is particularly relevant when signal reception or transmission is required from multiple horizontal directions without using a directional antenna.

The AOA-2458-59-TSL features an RP-SMA Male connector for connection to equipment with a corresponding RP-SMA Female interface. Its 50-ohm impedance is an important consideration when selecting compatible RF equipment and connecting components. Measuring 22 mm in diameter and 260 mm in length, the antenna has a defined physical profile that can be considered when planning installation space and connector positioning. Its 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 dual-band operation, omnidirectional radiation pattern and RP-SMA connection make the AOA-2458-59-TSL a straightforward antenna option for configurations requiring these documented characteristics.
