Ubiquiti airMAX AM-5G19-120 - Sector antenna, White

The Ubiquiti airMAX AM-5G19-120 is a 5 GHz, 19.1 dBi, 120° dual-linear sector antenna designed for outdoor wireless infrastructure. It is used in point-to-multipoint (PtMP) deployments, where a central base station communicates with multiple client devices. The antenna operates in the 5.15 to 5.85 GHz frequency range and provides 19.1 dBi of gain to focus signal strength across its coverage area. Its dual-linear polarization—utilizing both vertical and horizontal signal paths—improves link reliability. This model is commonly used to extend coverage in wide-area wireless networks and serves as the primary antenna for base station installations.

The antenna is rated for wind speeds of up to 200 km/h. It connects to radio hardware via two RP-SMA connectors. Measuring 700 mm in width and 73 mm in height, the unit is intended for wall mounting. At 5.9 kg, it requires a secure mounting surface to ensure long-term physical alignment. The white housing is designed for outdoor use.

• 1.5:1 VSWR ensures efficient power transfer across the 5 GHz band.
