MikroTik MANTBox 12s 2.4GHz Dual-Polarisation Sector Integrated Antenna (RB911G-2HPnD-12S)

The MikroTik MANTBox 12s (RB911G-2HPnD-12S) is an all-in-one 2.4GHz dual-polarisation sector integrated antenna with a built-in RouterOS wireless radio. Designed for ISPs and WISPs across Uganda, Kenya, Tanzania, Rwanda, and East Africa, the MANTBox 12s combines a high-gain sector antenna and a powerful 802.11b/g/n radio into a single weatherproof unit — simplifying deployment and eliminating the need for a separate radio and pigtail cables.

With its 12dBi gain and dual-polarisation design, the MANTBox 12s is the go-to sector AP for ISPs building out subscriber-facing point-to-multipoint networks at 2.4GHz — especially in areas where 5GHz penetration is limited or where longer-range 2.4GHz coverage is needed for rural and peri-urban deployments.

Why the MANTBox 12s for East African WISP Networks?

The MANTBox 12s is built for the realities of ISP deployment in East and West Africa:

• All-in-one simplicity: No separate radio, no pigtail cables, no weatherproofing of connectors — one unit replaces what would otherwise be three separate components.
• 2.4GHz reach: 2.4GHz penetrates light foliage and provides longer range than 5GHz in rural environments — critical for Uganda, Kenya, and Tanzania deployments covering mixed terrain.
• 90° sector coverage: Four MANTBox 12s units per tower gives you full 360° omni-equivalent coverage with the gain, interference rejection, and capacity of directional sector antennas.
• RouterOS full feature set: Runs MikroTik RouterOS with full RADIUS, DHCP, firewall, queue, and API support — integrating directly with your ISP billing system via the RouterOS API.
• PoE-powered: Single Ethernet cable for power and data — clean tower installations with no separate power runs to the antenna.
