UBIQUITI NETWORKS AM-5G20-90 Sector Antenna 20dBi 5GHz MIMO AirMax, 90 °, rocket kit content_copy

The UBIQUITI NETWORKS AM-5G20-90 is a sector antenna for use in Point-to-MultiPoint (PtMP) networks in the 5-GHz frequency range. It serves as a base station in wireless networks and enables targeted coverage of areas with a horizontal beamwidth of 90°. The antenna is designed for outdoor use and features a robust mechanical design that withstands wind loads up to 200 km/h. The dual-linear polarisation with a cross-pol isolation of 28 dB ensures efficient signal transmission and minimises interference. The antenna is compatible with Rocket Prism 5AC systems and is used in combination with corresponding access points.

Applications

The AM-5G20-90 is designed for use in wireless infrastructures where broad but targeted coverage is required, for example in industrial or commercial areas, campus networks, or for supplying residential areas. The 90° sector coverage enables efficient use of frequency resources and uniform signal distribution within the covered area. The antenna is designed for use in wireless networks requiring high data rates and stable connections.

Functions and equipment in detail

The antenna provides a gain of 19.4 to 20.3 dBi, ensuring strong signal amplification and sufficient range for PtMP networks. The horizontal beamwidth is 91° (6 dB), the vertical beamwidth is 85° (6 dB), creating a broad yet focused radiation pattern. The electrical beamwidth is 4°, and the electrical downtilt is 2°, enabling precise alignment and optimal signal coverage. The maximum VSWR (Voltage Standing Wave Ratio) is 1.5:1, indicating good impedance matching and low reflections. The antenna is designed for the frequency range of 5.15 to 5.85 GHz, corresponding to the 5-GHz band.

Technology explained simply

The dual-linear polarisation means the signal is transmitted in two perpendicular polarisation directions (horizontal and vertical). This improves signal quality and reduces the effects of multipath propagation. The cross-pol isolation of 28 dB ensures the two polarisation components are largely separated, enhancing signal purity. The antenna is designed for outdoor use and features high mechanical stability, even in strong winds. The wind load is 115 N at a wind speed of 160 km/h, enabling secure mounting even in exposed locations.

Compatibility and accessories

The antenna is specifically developed for use with Rocket Prism 5AC systems. The delivery includes a universal mast mount, a RocketM mount, and weatherproof RF jumpers. These components enable easy and secure mounting on masts or other supports. The antenna is part of a larger wireless network and is used in combination with access points to ensure a stable and high-performance wireless connection.

Mounting and installation

Mounting is done on a mast or other suitable structure using the included mounts. The antenna is intended for horizontal alignment, with an electrical downtilt of 2° ensuring optimal signal coverage. The RF jumpers are weatherproof and enable a secure connection to the access point.

Advantages in operation

The AM-5G20-90 offers high signal strength and precise coverage, resulting in a stable and reliable connection. The robust construction and high wind load capacity ensure a long service life even under extreme weather conditions. The dual polarisation and high cross-pol isolation improve signal quality and reduce interference. The antenna is easy to install and requires no additional components, simplifying maintenance and operation.
