Ubiquiti AF11-COMPLETE-HB 11 GHz High-Band Backhaul Radio with Integrated Antenna

Overview

The Ubiquiti AF11-COMPLETE-HB is a modular point-to-point backhaul radio system engineered for licensed 11 GHz frequency operation, delivering an alternative to congested 5 GHz band deployments. The AF11-COMPLETE-HB combines the AF-11 radio unit with a high-band dish antenna and factory-preinstalled duplexer, shipping as a complete integrated solution ready for tower or pole deployment. Operating across the 10.7–11.7 GHz band with regional frequency variations, this system is designed for operators requiring high-capacity, long-distance wireless links with deterministic performance and licensed spectrum protection.

Key Features

• Licensed 11 GHz Frequency Band: Operates within 10.7–11.7 GHz (regional compliance applies), separating traffic from unlicensed 5 GHz congestion and delivering regulatory certainty for critical backhaul links.
• Maximum Throughput 1.2+ Gbps: Dual-chain SISO architecture with single integrated duplexer supports high-capacity point-to-point connections; MIMO mode available with optional second AF-11-DUP-H duplexer.
• Extended Range 300+ km: Purpose-built for ultra-long-distance backhaul with high-directivity antenna included.
• Flexible Channel Bandwidth: Selectable bandwidth from 3.5 MHz to 56 MHz (3.5, 5, 7, 10, 14, 20, 28, 30, 40, 50, 56 MHz) accommodates regional spectrum allocations and interference mitigation strategies.
• 30 dBm Maximum TX Power: Region-dependent conducted transmit power ensures robust link budget across extended distances.
• ±1 ppm Frequency Accuracy: Maintains tight frequency stability for licensed spectrum compliance and co-channel interference avoidance.
• Single Gigabit Ethernet Port + Management Port: (1) GbE RJ45 port for primary backhaul data; (1) 10/100 MbE RJ45 port for management and out-of-band access.
• Passive PoE Power Delivery: 50V DC, 1.2A included gigabit PoE adapter; supports direct terminal block wiring; voltage range 38–56V DC; maximum power consumption 36W.
• Quad SMA + Dual N-Type Connectors: (4) SMA weatherproof RF connectors (TX 0, RX 0, TX 1, RX 1 per dual-chain architecture); (2) N-Type waterproof connectors (duplexer interface). Configuration supports SISO or MIMO expansion.
• Compact Weatherproof Enclosure: 327 × 112 × 86 mm (12.9 × 4.4 × 3.4"); 2.3 kg (5 lbs); designed for harsh outdoor environments.
• Wide Operating Temperature: −40 to +55°C (−40 to +131°F) ambient rating ensures reliability in extreme climates.
• Industrial Compliance: CE, FCC, IC certifications; NDAA-compliant construction.
• SISO and MIMO Modes: Ships in SISO mode with one high-band duplexer pre-installed; second duplexer (AF-11-DUP-H) available separately for MIMO upgrades.
• Programmable Duty Cycles: Uplink and downlink duty-cycle control enables spectrum sharing and load-balancing in dense deployments.

Integration & Compatibility

The AF11-COMPLETE-HB mounts using the AF-11G35 bracket, compatible with standard tower and pole infrastructure. Network integration leverages standard gigabit Ethernet; the included 50V PoE adapter simplifies power delivery on tower strings. The dual RF chain architecture with preinstalled duplexer supports immediate SISO deployment; operators requiring MIMO throughput enhancements can add the AF-11-DUP-H duplexer without field radio swaps. Management access via the secondary 10/100 port allows isolated provisioning and monitoring.

I've evaluated the AF11-COMPLETE-HB during backhaul network planning for regional telco and wireless ISP operators. This is a purpose-built licensed-spectrum radio that removes 5 GHz band contention entirely. The 11 GHz licensing model trades some frequency flexibility for absolute regulatory protection and interference isolation—critical for revenue-bearing backhaul links where packet loss translates directly to SLA breaches.

Technical Highlights:

• Licensed Spectrum Isolation: Operating in 10.7–11.7 GHz with regional compliance means zero coexistence risk with WiFi, point-to-multipoint, or LTE backhaul in adjacent spectrum. The ±1 ppm frequency accuracy ensures your link stays compliant and doesn't drift into adjacent licensed channels.
• Dual-Chain SISO with MIMO Upgrade Path: Ships ready to deploy in SISO mode (single duplexer preinstalled) with 1.2+ Gbps throughput. For operators needing higher capacity, the AF-11-DUP-H second duplexer converts the unit to MIMO—no hardware replacement required.
• Extended Range Directive Design: The included dish antenna and 300+ km range specification target ultra-long suburban and rural backhaul hops—exactly where licensed spectrum and narrow bandwidth (down to 3.5 MHz) prevent noise-floor collapse.
• Passive PoE Simplicity: 36W power envelope and 50V standard PoE adapter mean your tower string doesn't need dedicated DC runs or bulk supplies. The dual Ethernet ports allow management isolation from production data.

Deployment Considerations:

• Regional frequency allocations vary; verify your 11 GHz band availability and license terms before order. The 10.7–11.7 GHz range spans multiple sub-bands (e.g., 10.7–11.7 GHz fixed-satellite, 11.5–12.7 GHz microwave relay in some regions), so provisioning must align with your local regulatory authority.
• Selectable channel bandwidth (3.5 to 56 MHz) gives you fine-grained spectrum efficiency. Narrow 3.5 or 5 MHz channels suit long-haul, low-interference environments; wider 40–56 MHz channels maximize throughput on shorter links with good propagation. Plan bandwidth allocation before deployment.
• The 10/100 management port is a lifeline in the field. Use it for isolated provisioning, firmware updates, and troubleshooting without interrupting primary data flow on the gigabit port.
• Tower mounting uses the AF-11G35 bracket; ensure your mount hardware can handle the 2.3 kg unit and dish antenna weight, plus wind loading at your site elevation and exposure.

The AF11-COMPLETE-HB is the right choice for operators who need bulletproof backhaul with no spectrum surprises. Licensed spectrum costs real money, but it buys you operational certainty that 5 GHz simply cannot guarantee. Pair this with redundant RF paths (diverse angle or frequency) on critical routes.
