The Ubiquiti airMAX AM-5G19-120 is a high-performance sector antenna designed for carrier-class Point-to-MultiPoint (PtMP) wireless networks. Operating over the 4.9–5.9 GHz frequency band, this antenna provides approximately 19 dBi gain with a 120° horizontal beamwidth, enabling broad sector coverage ideal for base station deployments.

Featuring 2x2 dual-linear polarization, the AM-5G19-120 enhances spatial multiplexing, improving network capacity and interference rejection in dense environments. Its rugged mechanical design ensures reliable outdoor operation with weather resistance and wind survivability rated at approximately 200 km/h. The antenna includes a built-in RocketM mounting bracket for seamless integration with Ubiquiti Rocket radios, simplifying installation without the need for additional tools.

Additional technical highlights include a vertical beamwidth of roughly 4°, electrical downtilt of about 2°, cross-polarization isolation of ≥28 dB, and a maximum VSWR of ~1.5:1. The package typically includes necessary mounting hardware such as a universal pole mount, Rocket bracket, and weatherproof RF jumpers.

Ideal for wireless internet service providers and enterprises looking to build robust outdoor wireless networks, the AM-5G19-120 balances high gain, wide coverage, and ease of installation in a durable form factor.
