The product AM-5G19-120 from UBIQUITI NETWORKS is a sector antenna for outdoor use in Point-to-MultiPoint (PtMP) networks. It is specifically designed for operation in the 5 GHz frequency band and offers a beamwidth of 120° with a gain of 18.6 to 19.1 dBi. The antenna features dual-linear polarisation with a cross-pol isolation of 28 dB, enabling efficient use of the frequency spectrum and reducing interference. The robust mechanical design is intended for use under harsh environmental conditions, including high wind speeds up to 200 km/h.

Applications

The antenna is suitable for covering large areas in PtMP networks, for example in industrial communication, supplying residential areas, or in outdoor wireless network infrastructure. The 120° sector coverage enables uniform signal distribution over a wide angle, allowing multiple end devices or access points within a sector to be served. The antenna is compatible with the Rocket Prism 5AC system, making it suitable for integration into existing Ubiquiti networks.

Features and Equipment in Detail

The antenna provides 2x2 dual-polarisation performance, meaning two independent polarisation planes (horizontal and vertical) are transmitted simultaneously. This increases channel utilisation and improves signal quality. The electrical beamwidth is 4°, and the electrical downtilt is set at 2°, ensuring precise alignment and optimal signal transmission. The maximum VSWR (Voltage Standing Wave Ratio) is 1.5:1, indicating good impedance matching and low reflections.

Technology Explained Simply

The antenna operates in the 5.15–5.85 GHz frequency range, a band commonly used for wireless networks outdoors, as it offers a good balance between range and bandwidth. The gain of 18.6 to 19.1 dBi means the signal is amplified, increasing range and signal strength. The dual-linear polarisation allows simultaneous transmission of two independent signals, increasing data rate and reducing interference. The cross-pol isolation of 28 dB ensures the two polarisation planes are largely separated, improving signal quality.

Compatibility and Accessories

The antenna is specifically developed for use with the Rocket Prism 5AC, an access point system from Ubiquiti. The package includes a universal mast mount, a RocketM mount, and weatherproof RF jumpers. These components facilitate mounting and installation on masts or other outdoor supports. The antenna meets the minimum required ETSI specification EN 302 326 DN2, ensuring compliance with European radio requirements.

Mounting and Installation

Mounting is done on a mast or other sturdy outdoor support. The included universal mast mount and RocketM mount allow flexible and secure fastening. The RF jumpers are weatherproof and designed for outdoor use, ensuring a reliable connection to the access point. The antenna is designed for wind speeds up to 200 km/h, with a wind load of 89 N at 160 km/h.

Operational Advantages

The antenna offers high signal stability and range due to its high gain and dual polarisation. The robust construction and weatherproof RF jumpers ensure reliable operation under various environmental conditions. The 120° coverage enables efficient servicing of multiple endpoints from a single location, simplifying network infrastructure. Compatibility with the Rocket Prism 5AC system facilitates integration into existing Ubiquiti networks.
