Before requesting a quotation
Share the distance between sites, mounting height, clear-line-of-sight status, target throughput and compatible radio preference.
The antenna is not a complete wireless link by itself. Radio units, power, Ethernet protection, cabling and installation services must be considered separately.
Direct answer for buyers
The Ubiquiti AF-5G23-S45 is a 5 GHz, 23 dBi directional antenna intended to be paired with a compatible wireless radio to form one endpoint of a point-to-point bridge or backhaul link. It is mainly used when two buildings, towers or operational sites need a focused outdoor wireless connection. It may suit WISPs, enterprises, campuses, hospitality properties, industrial facilities and temporary project locations. Before proceeding, buyers should confirm line of sight, link distance, Fresnel clearance, required capacity, local frequency permissions, radio compatibility, pole dimensions, grounding, surge protection and installation access. A site-specific link plan is more reliable than choosing an antenna from distance alone.
What the AF-5G23-S45 does
The antenna concentrates radio energy into a narrow directional beam rather than broadcasting broadly around the installation point. When fitted with a suitable radio and aligned with a matching endpoint, it can support a dedicated outdoor bridge between two locations. Typical roles include extending a network to another building, carrying backhaul traffic from an access network, connecting an operational site where trenching is difficult, or creating a resilient secondary path where the complete design supports that objective.
Its 23 dBi gain and 5.1 to 5.9 GHz operating range position it as a compact option for planned directional links. Actual throughput and usable distance depend on the selected radio, channel width, interference, local regulations, path quality and environmental conditions.
Who should consider it
The model is relevant to network teams that need a focused link but prefer a smaller dish than higher-gain airFiber X antenna options. It can be considered for roof-to-roof, mast-to-mast or tower-to-building projects where the link budget supports 23 dBi gain and where a 10-degree class beamwidth is appropriate for alignment and interference control.
It may not be the correct choice for every long-distance project. Very long paths, noisy environments, strict availability targets or difficult Fresnel clearance may require another antenna size, another frequency band, greater mounting height or an alternative connectivity design. FourTeck can help review these factors before a bill of materials is finalised.
Business challenge map
Connecting separate buildings
A planned wireless bridge can carry network traffic across a road, yard or property where new fibre construction is not immediately practical.
Extending backhaul capacity
The antenna can form part of a backhaul endpoint when paired with the correct radio and a link budget that supports the required capacity.
Reducing rooftop footprint
Its compact low-profile format may be useful where mounting space and wind exposure are practical design concerns.
Managing co-location noise
Low sidelobes, directional focus and RF isolation can help, but frequency planning and site conditions still determine the result.
Core capabilities that matter in planning
Focused 23 dBi gain
Provides directional energy concentration for a point-to-point design. It does not by itself determine range or throughput.
5.1–5.9 GHz coverage
Supports a broad 5 GHz antenna range, subject to the capabilities of the radio and the rules that apply at the deployment site.
Integrated radome
The low-profile antenna incorporates environmental protection around the reflector and radio mounting area.
Dual-linear polarity
The slant-polarised design is intended for compatible airFiber X-style radio integration and 2×2 link operation.

Compatibility and scope dependencies
This product is an antenna, not a complete bridge. A usable deployment normally requires a compatible radio at each endpoint, suitable power injectors or power arrangements, outdoor shielded Ethernet cabling, surge protection, grounding, mounting hardware, a stable structure and accurate alignment. The current Ubiquiti store lists compatibility with selected platforms including AF-5XHD, RP-5AC-Gen2 and Wave-MLO5, but compatibility can change with product revisions and regional availability. Confirm the exact radio model, connector arrangement and firmware support before procurement.
Frequency permissions and maximum radiated power vary by jurisdiction. The radio configuration, antenna gain and operating channel must comply with local rules. FourTeck can assist with requirement review, but regulatory approval and site compliance should be confirmed by the buyer or the appointed project professional.

Directional performance and link planning
A 23 dBi antenna is useful because it concentrates energy in the intended direction and improves received signal relative to a lower-gain antenna, but antenna gain should never be treated as a stand-alone promise of distance. A correct design considers free-space path loss, terrain, antenna heights, the Fresnel zone, channel bandwidth, receiver sensitivity, transmit power, regional EIRP limits and environmental fade margin. The AF-5G23-S45 has a published 10-degree beamwidth for both slant polarisations. This offers a practical balance: it is directional enough to isolate a link from many off-axis signals, yet generally easier to align than the narrower beam of a much larger high-gain dish.
For a business buyer, the important question is not simply “How many kilometres can it reach?” The more useful question is “Can this antenna, with the selected radio and site conditions, meet the required capacity and availability target?” A short path in a congested area can be more difficult than a longer rural path with clean spectrum. Likewise, a clear visual line of sight does not automatically mean that the Fresnel zone is adequately clear. Trees, parapet walls, cranes, new construction and seasonal vegetation can all affect the path. FourTeck can use the information supplied by the customer to guide product selection and determine whether a formal site survey or professional link plan should be included.
Compact construction for outdoor sites
The AF-5G23-S45 uses a low-profile reflector with an integrated radome. This matters when the mounting location is exposed to dust, wind and changing weather conditions. The radome helps shield the radio area and reflector, while the protective shroud covers cables and connectors. The published weight is 3.4 kg with the mount, and the antenna is designed for poles with a diameter from 38 to 64 mm. These dimensions make it easier to consider for smaller rooftop masts and crowded structures than larger 30 or 34 dBi dishes, although the mounting structure still needs a proper engineering and safety review.
Wind survivability and wind-loading figures describe the antenna under specified conditions; they do not certify the mast, wall bracket, roof anchor or tower. The complete mounting system must be appropriate for local wind exposure and building requirements. Installers should also protect the reflector from deformation because dish shape directly influences antenna performance. Safe access, fall protection, grounding, lightning protection and outdoor cable routing should be part of the work method. In Dubai and other UAE environments, heat, dust and rooftop exposure add practical reasons to choose suitable outdoor cabling, weather sealing and periodic inspection.
RF isolation in busy wireless environments
Directional antennas are often deployed on rooftops or towers that already host several radios. In these environments, interference management can determine whether a link remains stable during busy periods. The AF-5G23-S45 is designed with low sidelobes and high isolation characteristics that can help limit unwanted energy outside the main beam. Its dual-linear slant polarisation supports compatible 2×2 radio operation. These characteristics are useful, but they do not replace site-specific RF planning.
Good co-location practice can include physical separation, careful antenna orientation, channel coordination, power control and monitoring of noise levels. The cleanest available frequency should be selected within the rules of the country and the capabilities of the radio. Where spectrum is heavily congested, a different frequency band, licensed solution, narrower beam antenna or fibre connection may offer a better result. Buyers should share details of existing radios at both sites, including frequency bands and mounting positions, so that compatibility and potential self-interference can be considered before equipment is ordered.
Ideal business environments and use cases
Campus and education sites
Connect administration, teaching, accommodation or security buildings where a planned outdoor bridge is suitable and trenching would disrupt operations.
Warehouses and logistics yards
Extend network access between offices, gates and storage buildings, subject to clear path, moving-crane considerations and appropriate mounting.
Hospitality properties
Link separated resort, service or accommodation buildings while keeping the bridge independent from guest access design and internal Wi-Fi planning.
WISP backhaul
Create a focused backhaul endpoint between network locations where the link budget and selected airFiber-compatible radio support the target capacity.
Construction and temporary sites
Provide connectivity during a project phase when towers, cranes and future structures are included in the path assessment and relocation plan.
Video surveillance backhaul
Carry aggregated camera traffic from a remote area after bandwidth, latency, multicast behaviour, retention architecture and failover needs are calculated.
Integration and operational considerations
The antenna becomes part of a network only when the complete radio bridge is configured. Network architects should determine whether the wireless link will operate as a transparent Layer 2 bridge, a routed connection, a VLAN trunk or a dedicated transport path. Loop prevention, spanning-tree design, Quality of Service, management access and monitoring should be defined before installation. The bridge capacity must be compared with real application demand, not only a headline radio rate. Voice, surveillance, cloud access and backup traffic may have different sensitivity to latency, jitter and packet loss.
Power resilience is equally important. If the link supports a critical process, both endpoints may require protected power, UPS capacity and a documented recovery procedure. Outdoor Ethernet surge protection and grounding should follow local electrical codes and the manufacturer’s installation guidance. Management credentials, firmware policy, configuration backups and alerting should be included in the handover. Buyers requesting installation can ask FourTeck to define the scope for mounting, cabling, alignment, radio configuration, network integration, testing and documentation separately so responsibilities are clear.
Questions to resolve before ordering
Provide coordinates or site addresses rather than an approximate driving distance.
Visual line of sight is only the starting point; obstructions around the path also matter.
Separate current average use, busy-hour demand and future growth.
Confirm exact model, firmware, connector arrangement and regional support.
A critical service may need redundancy, backup power and proactive monitoring.
Clarify rooftop access, safety approvals, grounding, cabling and handover responsibility.

How FourTeck can assist
FourTeck can support the buying process by clarifying the requirement, checking the exact model, reviewing compatible radio options and helping structure the bill of materials. This can include discussion of antennas, radio units, power components, outdoor cabling, Ethernet surge protectors, grounding materials, mounts and any requested installation services. For projects that need design assistance, the buyer can provide endpoint coordinates, photographs, mounting heights, existing equipment and target capacity so the practical planning questions can be identified early.
Quotation support can be separated into product supply, delivery coordination, installation, configuration, testing and handover. This makes it easier for procurement teams to compare the complete project scope rather than comparing antenna prices alone. FourTeck also supports broader business technology requirements through its technology product portfolio, installation and configuration services and UAE technology solutions. The final recommendation remains dependent on the actual path, regulatory conditions and operational target.
UAE availability and support guidance
Contact FourTeck to confirm current UAE availability for the AF-5G23-S45, the required quantity and compatible radio options. Availability may depend on vendor lead time, region, model revision and project volume. Delivery coordination can be discussed after the destination, quantity and required date are confirmed. Where installation is needed, include rooftop access, mounting, cable routing, grounding, alignment, configuration and testing in the quotation request. Businesses in Dubai, Abu Dhabi, Sharjah and Ajman can present one combined requirement for review, allowing product supply and service scope to be coordinated around the same design assumptions.
GCC Availability
FourTeck can assist organisations planning AF-5G23-S45 deployments across GCC markets by reviewing the intended link, exact antenna and radio pairing, required quantity, delivery destination and installation expectations. Projects in the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain and Oman may be subject to different frequency rules, import processes, vendor channels and service arrangements. Product availability, permitted channel use, delivery schedules, project visits and lead times therefore need to be confirmed for each destination. Buyers should provide the country, site coordinates, quantity, preferred radio, target capacity, mounting conditions and expected project timeline. FourTeck can then coordinate quotation guidance, configuration scope and regional project planning without assuming that one country’s stock status, certification or delivery estimate applies to another. For Kuwait-related enquiries, buyers may also review FourTeck Kuwait technology support.
Africa Availability
FourTeck can help organisations in African markets evaluate the AF-5G23-S45 as part of a complete point-to-point wireless requirement. Planning may include antenna and radio selection, accessories, power, grounding, mounting, configuration, support and renewal of related network services. Availability and fulfilment can vary with destination, quantity, radio region, power standards, shipping arrangements, vendor lead time and local installation conditions. Buyers should share the destination country, endpoint locations, required quantity, desired deployment schedule and any need for installation or remote configuration assistance. This information helps avoid treating the antenna as a stand-alone purchase when the project needs a complete link design. Regional resources include FourTeck Africa technology solutions, Kenya project coordination and Uganda technology support.
