MikroTik mANTBox 2 12s 2.4GHz 802.11b/g/n 120° Sector Outdoor Base Station

The MikroTik mANTBox 2 12s is a purpose-built outdoor wireless base station that merges a high-performance 2.4GHz sector antenna with a capable wireless router in one integrated enclosure. It builds on MikroTik's mANT antenna series, adding onboard processing and RouterOS to create a self-contained access point that is straightforward to deploy and manage.

Wireless Performance

The mANTBox 2 12s operates in the 2.4GHz band using a dual-chain radio based on the AR9342 wireless chip, supporting the 802.11b/g/n (Wi-Fi 4) standard for broad client compatibility. The integrated dual-polarisation sector antenna provides 12 dBi of gain across a 120° horizontal beamwidth, enabling long-range coverage while maintaining a focused sector pattern that reduces interference compared to omnidirectional alternatives. Maximum wireless data rate is 300 Mbit/s. Receive sensitivity spans from -100 dBm at 1 Mbit/s (802.11b) to -73 dBm at MCS7 (802.11n), supporting reliable links at extended ranges.

Processing & Storage

The unit is powered by an AR9342 processor running at 600 MHz on the MIPSBE architecture, with 64 MB of RAM and 128 MB of NAND flash storage. RouterOS comes pre-installed and licensed — no additional software purchase is required. RouterOS provides comprehensive networking features including routing, bridging, firewall, QoS, VPN, and full wireless management, accessible via WinBox, WebFig, or CLI.

Ethernet & Powering

A single 10/100/1000 Gigabit Ethernet port handles both data connectivity and power input. The mANTBox 2 12s accepts two forms of power input: passive PoE via the Ethernet port (10–28 V) or a DC jack (8–30 V), providing flexibility for different installation scenarios. Maximum power consumption is 11 W. The unit is passively cooled, ensuring silent and maintenance-free operation in outdoor environments.

Monitoring & Diagnostics

On-board diagnostics include a PCB temperature monitor, voltage monitor, and a beeper, providing useful feedback for installation alignment and ongoing health monitoring without requiring additional tools.

Build & Installation

The mANTBox 2 12s is housed in an IP54-rated outdoor enclosure measuring 140 × 348 × 82 mm, tested across an ambient temperature range of -40°C to 70°C — suitable for challenging outdoor climates. MTBF is rated at approximately 100,000 hours at 25°C. The package includes a Gigabit PoE injector, a QMP pole mounting bracket, a 24V 0.8A power adapter, a metal mounting ring, and a K-41 fastening set for straightforward pole installation.

Use Cases

The mANTBox 2 12s is well suited for wireless ISP base station deployments, outdoor public access hotspots, point-to-multipoint sector coverage in the 2.4GHz band, and any scenario where long-range 2.4GHz sector coverage is required from a single integrated unit. Its 120° beamwidth makes it a natural fit for three-sector deployments providing full 360° coverage around a tower or rooftop.
