Product Review

The Aruba AP-ANT-28 antenna is designed for both 2.4-GHz and 5-GHz frequencies, offering sector coverage with dual-polarized, 60° beamwidths, making it suitable for Wi-Fi access in targeted areas. However, the need to purchase the Azimuth/elevation mount kit separately for wall and pole installation could be a drawback for those seeking an all-in-one solution. Its construction features an aluminum housing with a plastic radome and supports a wide operating temperature range from -45° C to 65° C, ensuring durability and reliability across various environmental conditions.


The Aruba AP-ANT-28 is a dual-polarized antenna designed to enhance Wi-Fi coverage across both 2.4-GHz and 5-GHz bands. This antenna is an optimal solution for achieving sector coverage in various deployment environments. With its 60° horizontal and vertical beamwidths, it effectively distributes Wi-Fi signals in targeted areas, ensuring efficient and reliable wireless connectivity. One of the key features of the AP-ANT-28 is its frequency range and gain. It operates within the 4.9-6.0 GHz frequency band with a minimum gain of 7.5 dBi, and also supports the 2.4-2.5 GHz band with a similar minimum gain of 7.5 dBi. This wide frequency range coupled with a decent gain makes it versatile for different wireless applications, ensuring robust signal strength and coverage. The antenna's physical dimensions are compact, measuring 197.5 mm in width and depth, and 34.5 mm in height, which allows for easy placement and integration into various environments. Despite its small size, it has a significant weight of 489 g, attributing to its quality build materials, including an aluminum housing for the antenna and a plastic radome that protects the antenna elements from environmental factors. Polarization is another critical aspect of the AP-ANT-28, featuring slant +/- 45° polarization. This characteristic helps in reducing interference and improving the reliability of wireless connections in densely populated areas. The antenna is equipped with pigtail cables that terminate in RP-SMA male connectors, measuring 75 cm in length, facilitating easy and flexible connections to Wi-Fi access points. The antenna's maximum input power is 6 watts, allowing it to handle ample power for broadcasting Wi-Fi signals efficiently. It operates within a wide temperature range, from -45° C to 65° C, making it suitable for various outdoor and indoor environments. The antenna's VSWR is rated at 2:1 max, indicating a low level of reflection and better transmission efficiency. For installation, the AP-ANT-28 ships with wall anchors, making it ready for immediate mounting. For more versatile mounting options, an azimuth/elevation mount kit for wall and pole mounting is available separately under the model AP-ANT-MNT-3. This additional hardware facilitates precise orientation of the antenna for optimal signal distribution. Key hardware specifications include: - Dimensions: 197.5 mm (W) x 197.5 mm (D) x 34.5 mm (H) - Weight: 489 g (1.1 lbs) - Beamwidth: 60° Horizontal and Vertical Overall, the Aruba AP-ANT-28 stands out as a high-performance antenna, designed for enhancing Wi-Fi coverage in both 2.4-GHz and 5-GHz sectors. Its durable construction, combined with versatile mounting options and efficient signal distribution capabilities, makes it a suitable choice for a wide range of wireless networking applications.
