## Long description

The UBIQUITI airMAX ac 2x2 directional antenna delivers up to 21 dBi gain across the 5.1–5.8 GHz band in a compact white enclosure (750 × 173 × 78 mm). Engineered for outdoor wireless deployments, this dual-polarization antenna provides a 60° horizontal beamwidth and is intended for point‑to‑point and sector links where increased coverage, throughput and interference rejection are required. The integrated mount supports direct attachment of compatible Rocket base stations, enabling straightforward installation for fixed wireless networks.
Advantages
This antenna offers carrier-class mechanical construction with an innovative deflector design and 2x2 dual-polarity performance that improves link reliability. Reduced sidelobes and backlobes decrease susceptibility to noise from nearby radios and co‑location sites, improving signal quality in dense deployments. The antenna’s compact, weather-ready enclosure and built-in mount simplify outdoor installation and integration with Rocket radios for Point‑to‑MultiPoint networks.
Suitable for
Outdoor point-to-point wireless links
Sector coverage in Point‑to‑MultiPoint (PtMP) deployments
Fixed wireless access where dual-polarization is required
Environments requiring improved noise immunity and stable beam performance

How to use
Mount the antenna outdoors on a suitable pole or wall bracket using the integrated Rocket-compatible mount. Align the antenna to the intended coverage sector or link direction to achieve the desired beam orientation, and secure fasteners to maintain stable alignment in outdoor conditions. Connect the antenna to the compatible Rocket or Rocket5ac radio following the radio manufacturer’s instructions for cabling, grounding and lightning protection. Verify VSWR and link performance during commissioning and make fine alignment adjustments as needed to maximize throughput and signal stability.
Usage recommendations
For optimal performance in PtMP networks, pair this airMAX ac antenna with a Rocket5ac radio and position antennas to minimize obstruction and co‑site interference. Use proper grounding and surge protection for outdoor installations, and periodically inspect mounts and seals to maintain weatherproofing and mechanical integrity.
