Antena UBIQUITI airMAX ac 2x2 21 dBi, dupla polarização, 5,1–5,8 GHz, 60°x60°, montagem na parede, branco

The Ubiquiti airMAX ac 2x2 21 dBi sector antenna (model AM-5AC21-60) operates in the 5.1–5.8 GHz band and provides dual-polarity 2x2 performance with a maximum gain of 21 dBi. Designed for Point-to-MultiPoint (PtMP) networks, it offers a 60° horizontal beamwidth, a VSWR of 1.5:1, compact dimensions (173 × 78 × 750 mm) and an integrated Rocket™ mount for tool-free installation. The antenna is constructed for outdoor use and is compatible with RocketM5 models, although optimal performance is achieved with Rocket5ac radios.

Advantages

The airMAX ac antenna combines carrier-class mechanical construction with an innovative deflector design to deliver improved beam performance and reduced sidelobes and backlobes for superior noise immunity in co-location deployments. Dual-polarity 2x2 operation supports robust signal transmission and scalability in multi-sector PtMP setups. The built-in Rocket mount simplifies installation and reduces deployment time.

Suitable for

• Point-to-MultiPoint (PtMP) base stations for wireless ISPs
• Sectorized deployments requiring high gain and noise rejection
• Outdoor wireless links operating in the 5.1–5.8 GHz band
• Installations using Ubiquiti Rocket5ac radios (compatible with RocketM5)

How to use

Mount the antenna outdoors on a suitable pole or wall bracket, ensuring clear line-of-sight to client devices where possible. Attach a compatible Rocket radio directly into the integrated Rocket™ mount until it locks in place; no additional tools are required for securing the radio. Orient the sector antenna to cover the intended service area (60° horizontal beamwidth) and connect RF and power components according to the Rocket radio installation guide. Perform alignment and link testing using the radio’s management interface.

Recommendations

For best performance use the AM-5AC21-60 with Rocket5ac radios, place antennas to minimize co‑location interference, and maintain regular inspection of mounts and RF connections in harsh outdoor environments.
