Ubiquiti AF‑5G30‑S45: High-Performance 5GHz 30dBi Antenna for Long-Range Wireless Backhaul

Product Description

In today’s interconnected world, establishing reliable high-throughput wireless links over long distances is critical—whether for internet service providers, enterprise networks, or remote surveillance systems. The Ubiquiti AF‑5G30‑S45 is a purpose-built, high-performance antenna that supports such infrastructure by delivering exceptional signal gain, directionality, and resilience. It’s specifically engineered to pair seamlessly with Ubiquiti’s AirFiber X radios, providing a robust and scalable solution for point-to-point (PtP) backhaul applications.

Designed with both performance and durability in mind, the Ubiquiti AF‑5G30‑S45 empowers users to extend network reach across vast terrains with exceptional signal integrity and minimal interference.

Designed for Long-Distance Point-to-Point Applications

The Ubiquiti AF‑5G30‑S45 is a 30 dBi parabolic dish antenna that operates in the 5.1–5.9 GHz frequency range, making it ideal for licensed and unlicensed deployments around the globe. With its narrow beamwidth of approximately 5.8°, it enables tight RF focusing, which is vital in reducing interference and ensuring solid signal transmission over long distances—often exceeding 10 km under ideal conditions.

This high-gain configuration ensures that signal energy is concentrated, allowing for powerful and efficient transmission that resists environmental degradation and maintains throughput consistency across extended links.

Optimized for AirFiber X Radios

This Ubiquiti AF‑5G30‑S45 antenna is engineered to integrate directly with Ubiquiti’s AirFiber X radios, a line of carrier-grade, high-throughput radios known for their efficiency and spectral performance. The synergy between the antenna and radio hardware simplifies installation and alignment, ensures perfect impedance matching, and reduces signal loss between components.

The dish includes a dedicated bracket and mounting plate to securely attach the AirFiber X unit, eliminating the need for additional adaptors or complex custom mounts.

Advanced RF Isolation and Dual-Slant Polarization

What sets the Ubiquiti AF‑5G30‑S45 apart from other parabolic antennas is its use of +45° and –45° slant polarization, which helps to improve cross-polarization isolation and signal discrimination in noisy environments. This dual-slant design significantly reduces interference when multiple antennas are co-located on a tower or mast.

Additionally, the antenna offers an excellent front-to-back ratio of 30 dB, ensuring that signals from behind are effectively rejected. This is particularly valuable in high-density deployment scenarios where reducing side and rear lobe interference is critical.

Furthermore, the antenna maintains a maximum VSWR of 1.6:1, ensuring minimal signal reflection and maximum power transmission, further contributing to overall link efficiency.

Industrial-Grade Construction and Weather Resistance

Field deployment requires hardware that can stand up to the elements, and Ubiquiti delivers on that front. The Ubiquiti AF‑5G30‑S45 features a durable, powder-coated aluminum dish that’s engineered to withstand harsh outdoor environments. Supporting hardware is made from galvanized and stainless steel, ensuring long-term resistance to corrosion and physical stress.

Key weather-resistant features include:

• Wind survivability up to 200 km/h (125 mph)

• Wind loading of 790 N at top wind speeds

• Protective shroud for shielding cables and connectors

• GEOMET-coated fasteners for extended corrosion protection

• UV-resistant materials and sealed components for long-term exposure

Its lightweight design (7.4 kg with mounting hardware) allows for easier tower installations while maintaining structural integrity under stress.

Simple, Precise Alignment

Proper alignment is essential for optimal PtP performance. Ubiquiti has equipped the Ubiquiti AF‑5G30‑S45 with an elevation angle adjustment mechanism and an integrated bubble level, streamlining the alignment process and minimizing installation time.

These features make the dish installer-friendly and reduce the need for external tools or guesswork during field deployments, ensuring a quick and professional-grade setup.

Real-World Applications

The Ubiquiti AF‑5G30‑S45 is used in a wide variety of real-world scenarios, including:

• ISPs building wireless backhaul links between towers, base stations, or central hubs

• Enterprises connecting remote offices or facilities across challenging terrain

• Surveillance and security teams maintaining high-definition video links across campuses or borders

• Redundant or emergency links where fiber or wired infrastructure is unavailable or unreliable

• Temporary deployments in disaster relief zones or construction sites

Because of its strong interference rejection, it is especially suitable for deployments in congested environments where multiple antennas or links operate in proximity.

Tested and Trusted by Wireless Professionals

The global user community has consistently highlighted the reliability and performance of the Ubiquiti AF‑5G30‑S45. In many forums and case studies, users have documented successful deployments over 8–10 km with strong throughput, minimal packet loss, and excellent uptime—especially when paired with Ubiquiti’s powerful AirFiber radios.

Despite the antenna’s high directional gain, its ease of alignment (thanks to its included elevation adjuster and bubble level) ensures that even less-experienced installers can achieve professional-grade results.

Simple Integration in Multi-Antenna Setups

Whether you’re outfitting a new tower or retrofitting an existing one, the Ubiquiti AF‑5G30‑S45 integrates smoothly into environments with multiple antennas. Its compact 650 mm diameter and exceptional front-to-back rejection reduce the impact of signal bleed between nearby devices. This is especially useful for operators who need to stack multiple point-to-point links on a single mast.

And because it’s purpose-built for the Ubiquiti AirFiber ecosystem, users benefit from consolidated management, diagnostics, and firmware updates across both radios and antennas.
