The UBIQUITI NETWORKS AF-5G34-S45 is a 5-GHz parabolic antenna for outdoor use, specifically designed for point-to-point (PtP) connections with high range. The device features dual-polarization performance in 2x2 mode and is intended for use with airFiber X radio devices. The antenna features a robust mechanical design suitable for installation in wind-loaded environments. Mounting is done via a universal mast mount included in the delivery, as well as a special airFiber radio mount and weatherproof RF jumpers, which are also included.

Applications

The antenna is intended for use in wireless networks in the frequency range of 5.1 to 5.9 GHz, particularly in industrial, telecommunications, or infrastructure applications where a stable, long-range connection is required. Due to its high gain of 34 dBi and dual-linear polarization, it is especially suitable for PtP connections where high signal quality and low interference are required. The construction with a 45-degree slant angle (Slant 45) enables use in systems requiring slanted polarization to minimize cross-polarization interference.

Functions and Equipment in Detail

The antenna provides a gain of 34 dBi, enabling strong focusing of the radio signal in one direction and thus increasing range and signal strength. The polarization is dual-linear, meaning the signal is transmitted in two perpendicular polarization directions to improve signal quality and reduce interference. The F/B ratio is 30 dB, ensuring low backward radiation and thus improved signal purity. The maximum VSWR (Standing Wave Ratio) is 1.6:1, indicating good impedance matching and thus efficient energy transfer.

Technology Explained Simply

The antenna operates in the 5-GHz frequency band, used for wireless communication with high bandwidth and low interference. The high gain of 34 dBi means the signal is strongly focused, increasing range and reducing sensitivity to interference. The dual-polarization function in 2x2 mode enables higher data rates and reliability by operating two independent signal channels in parallel. The construction with a 45-degree slant angle (Slant 45) is specifically designed for systems requiring slanted polarization to avoid cross-polarization interference. The antenna is designed for outdoor use and features a robust construction capable of withstanding wind speeds up to 200 km/h.

Compatibility and Accessories

The AF-5G34-S45 is specifically developed for use with airFiber X radio devices. The components included in the delivery package consist of a universal mast mount, a special airFiber radio mount, and weatherproof RF jumpers, ensuring a secure and weatherproof connection between the antenna and the radio device. The antenna complies with the ETSI specification EN 302 326 DN2, confirming conformity with European radio requirements.

Mounting and Installation

Mounting is done using the universal mast mount included in the delivery, enabling secure attachment to a mast. The airFiber radio mount ensures precise alignment of the antenna, while the weatherproof RF jumpers provide a reliable connection to the radio device. The antenna is designed for outdoor use and features a construction capable of withstanding wind loads of up to 790 N at 200 km/h.

Operational Advantages

The high gain of 34 dBi enables maximum range and signal strength, which is particularly beneficial for long PtP connections. The dual-polarization function in 2x2 mode improves signal quality and reliability. The robust construction and high wind load resistance ensure stable operation even under extreme weather conditions. The included mounting components and RF jumpers simplify installation and ensure a secure, weatherproof connection.
