Ubiquiti AP-5AC-90-HD | airPRISM 5AC HD Sector Antenna

A 5 GHz sector antenna that delivers 90° of high-density point-to-multipoint coverage from a single unit, suited to operators running dense client deployments on airMAX infrastructure.

Why this one

• Three discrete 30° sectors are housed in one enclosure, so you cover a 90° arc with separated RF paths rather than a single wide beam — which is what keeps co-channel interference manageable at high client counts.
• The 22 dBi gain figure gives meaningful reach for a sector antenna, so you're not sacrificing distance to get the density benefit.
• All mounting hardware and brackets are included, so there's nothing extra to source before you can get it on a tower or rooftop.

Good fit if you're running a Point-to-MultiPoint airMAX network where a single wide-beam sector is struggling under client density, and you need to reclaim per-client throughput without adding more physical mounting positions.

Worth considering something else if your site has few clients spread across a wide arc — a conventional sector antenna suits low-density deployments better and avoids the complexity of managing three independent RF paths.

What you'll also need

A compatible 5 GHz airMAX radio to drive the antenna — this is a passive antenna only — along with appropriate cabling and a PoE source for the radio itself.
