Aruba R4H28A

Overview

The Aruba R4H28A is an outdoor MIMO antenna designed to extend high-performance Wi-Fi 6 coverage in challenging outdoor environments. It delivers a focused directional signal with a 14 dBi gain and a 30-degree beamwidth both horizontally and vertically, which helps maintain stable connections over long distances while reducing interference. This antenna is ideal for use in large open areas such as streets, stadiums, and campuses where consistent wireless coverage is critical.

Built to withstand extreme weather conditions, it operates reliably in temperatures ranging from -49°F to 149°F. The antenna supports a frequency range of 4.9 to 6.0 GHz and is compatible with HPE Aruba AP-584 and AP-585 access points, making it a practical solution for expanding outdoor wireless networks with Wi-Fi 6 technology.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
