The Ubiquiti UniFi Swiss-Army Knife Ultra (Model: UK-Ultra) specification description follows:
The Ubiquiti UniFi Swiss-Army Knife Ultra (Model: UK-Ultra) is an ultra-compact, highly versatile Wi-Fi 5 (802.11ac) access point engineered for flexible indoor and outdoor coverage extension. Designed with an adaptable form factor and support for external antenna extensions, the UK-Ultra serves as an economical, enterprise-grade solution for high-density, targeted wireless deployments, long-range outdoor links, and low-profile mounting setups.
Featuring 2x2 MIMO dual-band spatial streams (2.4 GHz and 5 GHz), the UK-Ultra delivers an aggregate wireless throughput rate of up to 1.15 Gbps. Equipped with a Gigabit Ethernet RJ45 uplink port supporting 802.3af PoE input, it features an IPX6 outdoor-rated weatherproof housing, internal high-efficiency panel antennas, dual RP-SMA connectors for optional external directional or omni antennas, and seamless integration into the UniFi Network Application.
Comprehensive Key Features:
- Adaptable Multi-Antenna Architecture: Operates using high-efficiency internal panel antennas or connects to optional external high-gain antenna accessories via dual RP-SMA ports.
- 1.15 Gbps Aggregate Wireless Speed: Delivers up to 300 Mbps on the 2.4 GHz frequency band and up to 867 Mbps on the 5 GHz band for reliable wireless coverage.
- IPX6 Weatherproof Enclosure: Ruggedized, weather-resistant plastic construction engineered to withstand heavy rain, wind, and harsh environmental outdoor exposure.
- Compact & Low-Profile Physical Form Factor: Small physical footprint enables discrete indoor or outdoor installations on walls, poles, or drop-ceiling rails.
- Power over Ethernet (802.3af PoE) Powered: Receives power and data backhaul over a single Gigabit Ethernet RJ45 cable connection.
- Long-Range Coverage Capability: Supports up to 115 m² (1,250 ft²) of wireless coverage using internal antennas, expandable via optional sector or omni antenna attachments.
- Centralized UniFi Network Integration: Managed through the UniFi Network Application for centralized site deployment, dynamic channel selection, guest portal management, and real-time network telemetry.
