Exact compatibility confirmation
Direct answer for buyers
The PBE-5AC-400-FEED is the feed and radio assembly used with the earlier Ubiquiti PowerBeam 5AC 400 reflector system. Its main role is to provide the active wireless and Ethernet component within a compatible outdoor point-to-point or point-to-multipoint installation. It is most relevant to organisations repairing or supporting an existing link rather than planning a new deployment. Before proceeding, confirm that the required part is specifically PBE-5AC-400-FEED, not the complete PBE-5AC-400 bridge, a PowerBeam M5 feed, an ISO model or a later Gen2 unit. Buyers should also verify regional firmware restrictions, physical condition, reset access, included components and whether the existing dish and mounting assembly remain serviceable.
What this component does
The feed assembly contains the active radio electronics and connects to the reflector system that forms the directional PowerBeam antenna. In a compatible installation, it supports a focused 5 GHz wireless link while providing a Gigabit Ethernet interface for network connectivity and passive PoE power. The reflector, mounting system and careful alignment work together with the feed to achieve the intended directional performance. Replacing only the feed may allow an organisation to restore a link while retaining a serviceable dish and mount, but this should be treated as a repair decision rather than an automatic drop-in replacement.
Because this SKU belongs to an older PowerBeam generation, a technician should compare the existing hardware label, connector arrangement, firmware family and mechanical fit. Similar-looking PowerBeam products are not necessarily interchangeable. A successful repair also depends on the condition of the Ethernet cable, surge protection, PoE source, grounding, dish, brackets and remote link endpoint.
Who should consider it
This component may suit wireless internet providers, system integrators, industrial sites, warehouses, hospitality properties, schools, farms, campuses and commercial facilities that already operate a confirmed PBE-5AC-400 installation. It may also be useful as a controlled spare for a legacy estate where immediate migration is not yet practical.
It is generally not the preferred starting point for a new wireless project. New links benefit from a current design review covering spectrum conditions, distance, line of sight, throughput, redundancy, management platform and lifecycle expectations. Buyers without an existing 400 mm reflector and compatible mounting hardware should request a complete bridge recommendation rather than purchasing a feed alone. FourTeck can help compare repair, replacement and modernisation options without assuming that the oldest component is automatically the lowest-risk choice.
Business challenges this purchase may address
Failed radio with reusable dish
Where testing confirms that the feed electronics have failed but the reflector and mount remain structurally sound, a matched replacement feed may restore service without replacing every mechanical component.
Legacy spare requirement
Operators supporting several older links may need a tested spare to reduce the operational impact of a failure while a wider migration plan is prepared.
Controlled maintenance budget
A component repair can be considered where a full redesign is not currently approved, provided the lifecycle, condition and compatibility risks are understood.
Link fault isolation
A known-good compatible feed can help qualified technicians distinguish radio failure from cabling, PoE, alignment, interference or remote-end faults.
Product-fit matrix
| Requirement | Suitable when | Confirm before ordering |
|---|---|---|
| Repair an existing PBE-5AC-400 | The installed label and mechanical assembly match the requested feed | Regional version, firmware access, radio condition and physical fit |
| Purchase a complete wireless bridge | Not suitable as a standalone feed-only order | Request dish, mount, PoE, cabling and full bill of materials |
| Maintain legacy spares | Your estate still contains verified PBE-5AC-400 units | Quantity, test status, storage policy and migration plan |
| Build a new long-term link | Usually better served by a current platform assessment | Distance, bandwidth, spectrum, redundancy and lifecycle targets |
Compatibility and scope notice
Do not order this feed solely because another device has a similar 400 mm dish. PowerBeam M5, PowerBeam AC, ISO and Gen2 families can differ in electronics, enclosure details, region coding and supported software. The safest process is to provide a clear photograph of the existing product label, the front and rear of the feed, the dish assembly and the PoE injector. Confirm whether you require only the feed, a tested replacement, a complete radio and reflector, or a modern link replacement. A feed-only listing should not be interpreted as including a reflector dish, mounting bracket, pole hardware, radome, PoE adapter, mains cable, surge protector or Ethernet cable unless these are written into the quotation.
A practical repair and purchase journey
Identify the installed unit
Record the complete label, country code, MAC address, dish diameter, feed shape and existing power injector details.
Confirm the fault
Test cabling, PoE voltage, surge protection, reset response, local Ethernet access and the remote endpoint before condemning the feed.
Review the offered component
Confirm condition, test status, region, included cap or hardware, warranty terms and return conditions for the quoted unit.
Plan installation and alignment
Back up configuration where possible, use safe working practices, weatherproof the cable entry and realign both ends of the link after replacement.
Validate service
Check signal levels, noise, modulation, capacity, packet loss, management access and performance during representative traffic conditions.
Directional link performance depends on the full system
The feed is only one part of the radio path. The reflector geometry, alignment, clear line of sight, Fresnel-zone clearance, channel width, interference, cable quality and remote endpoint all influence the link. Replacing the feed will not correct a blocked path, badly twisted mount, congested spectrum or damaged Ethernet run. Before authorising a component purchase, compare current and historical signal data and inspect the complete installation. A small alignment error on a directional dish can create a significant performance loss, particularly over longer distances.
Legacy management and firmware planning
A vintage radio may run an older airOS branch and may have different upgrade limits from current UISP wireless products. Confirm that your operations team can access, configure and monitor the replacement within the existing environment. Save the current network settings, wireless parameters and device credentials before replacement where possible. Do not assume that a configuration backup from another model can be restored safely. Regional radio rules, channel options and transmit power limits must remain correctly configured for the deployment country.
Repair versus migration decision
A feed replacement can be reasonable for a stable, non-critical link with known requirements. A complete platform migration may be more appropriate where throughput needs have increased, replacement parts are difficult to source, security policy requires supported software, or the link serves a critical operation. Evaluate the cost of labour, access equipment, alignment and future outages alongside the component price. FourTeck can help frame this decision and prepare either a component quotation or a broader wireless bridge recommendation.

Procurement checklist
How FourTeck can assist
FourTeck can support the purchasing process by clarifying whether the request is for a feed assembly or a complete PowerBeam unit, reviewing identifying photographs, checking the required quantity and documenting what must be included in the quotation. Where a repair is planned, the scope can also cover installation coordination, configuration, alignment and basic service validation. These activities are not automatically included with every hardware quote and should be requested explicitly.
For a broader project, explore FourTeck’s business technology products, discuss installation and configuration services, or send the full requirement through the FourTeck contact team. Buyers planning a wider infrastructure refresh can also review the FourTeck technology portfolio.
UAE availability and support guidance
Contact FourTeck to confirm current UAE availability for PBE-5AC-400-FEED. Because it is a vintage item, availability may depend on remaining channel inventory, secondary-market sourcing, product condition, quantity, regional version and vendor lead time. The quotation should identify whether the offered unit is new old stock, refurbished or pre-owned, and should state included items and applicable return or warranty terms. Delivery and project coordination can be discussed after the exact requirement is confirmed. Installation and configuration scope should be included in the quotation when required rather than assumed to be part of a component sale.
Dubai, Abu Dhabi, Sharjah and Ajman coverage
Businesses in Dubai, Abu Dhabi, Sharjah and Ajman can contact FourTeck for requirement review, quotation coordination and delivery planning. For an existing outdoor link, provide the site location, roof or mast access details, photographs of both endpoints and a brief description of the fault. Where onsite work is requested, the service scope may depend on access permissions, working-at-height requirements, cable routes, weather conditions, alignment complexity and availability of a clear remote endpoint. A confirmed site and technical scope allows the quotation to separate hardware, delivery, installation, configuration and testing.
GCC availability
FourTeck can assist organisations across GCC markets with requirement review for legacy Ubiquiti components, model identification, quotation coordination and replacement planning. Buyers in the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain and Oman should provide the destination country, exact SKU, quantity, acceptable condition and expected deployment schedule. For PBE-5AC-400-FEED, regional coding and legacy availability deserve particular attention. Product supply, delivery schedules, service visits and vendor lead times can vary by country, quantity and source. Installation planning may also depend on site access, permits, mast height and the availability of technicians familiar with directional wireless alignment. FourTeck can discuss a feed-only replacement, a complete compatible bridge or a migration to a current platform. No local inventory, customs outcome or fixed delivery date should be assumed until the offered product and destination requirements are confirmed in writing. Kuwait-based requirements may also be discussed through FourTeck Kuwait resources.
Africa availability
Organisations planning legacy wireless maintenance in Africa can ask FourTeck to review the exact product requirement, destination, quantity, condition expectations and deployment constraints. The PBE-5AC-400-FEED may be relevant to selected existing installations, but sourcing can vary significantly because the SKU is vintage. Fulfilment may depend on the destination country, product region, shipping arrangement, import requirements, vendor lead time and whether a tested pre-owned component is acceptable. Buyers should also consider power quality, grounding, lightning protection, outdoor cabling, mounting condition and access to technicians who can align and validate the link. Share photographs of the installed device and explain whether the objective is emergency repair, planned spare holding or a full network refresh. FourTeck can help compare component replacement with current alternatives and document configuration or installation scope. Regional enquiries can use FourTeck Africa, FourTeck Kenya or FourTeck Uganda.

Frequently asked questions
Is PBE-5AC-400-FEED a complete PowerBeam?
No. The SKU identifies the feed assembly. Do not assume it includes the 400 mm reflector, mounting hardware, PoE injector, power lead, Ethernet cable or radome.
Is this model still current?
Ubiquiti lists PBE-5AC-400-FEED as a vintage airMAX product. Availability and support expectations should therefore be checked carefully.
Can it replace a PowerBeam M5 feed?
Do not assume compatibility. AC and M-series products differ, and the exact installed model must be confirmed from the label and hardware.
Can I use it for a new wireless link?
A vintage feed-only component is normally selected for maintenance. New links should be sized using a current complete platform and a link assessment.
What details are needed for a quotation?
Provide the exact label photograph, quantity, destination, acceptable condition, required included items and whether installation or configuration is needed.
Does the feed include a PoE injector?
A feed-only offer should not be assumed to include a PoE injector. The quotation must state the included components explicitly.
Will replacing the feed fix a weak link?
Only when the feed is the confirmed fault. Weak performance can also result from alignment, interference, obstruction, cable loss, power problems or a remote-end issue.
Is installation support available?
Installation, configuration and alignment can be discussed with FourTeck. The scope depends on site access, safety requirements, cable condition and both link endpoints.
What warranty applies?
Warranty depends on the condition and source of the offered unit. Confirm the written warranty and return terms in the quotation.
