Alfa Network Tube 2H – Outdoor 2.4GHz 802.11n Access Point for Long-Range Wireless Networks

The ALFA Network Tube 2H is a high-power outdoor long-range Wi-Fi adapter and access point designed for wireless coverage deployment in exterior environments where standard indoor equipment cannot deliver the required range. Widely used by WISPs, network integrators, and wireless system installers for point-to-point links and directional outdoor coverage, it combines high transmit power with full antenna flexibility.

Built on the Atheros AR9331 chipset, the platform delivers stable operation and broad compatibility with alternative firmware including OpenWRT. The weatherproof sealed enclosure supports permanent outdoor installation without additional protection. The N-type antenna connector accommodates any external antenna type — omnidirectional, sector, or directional panel with MIMO support. Power is supplied via Ethernet cable with PoE, with a PoE injector included for installations without a dedicated PoE switch. The USB 2.0 interface enables direct connection to a computer as a high-power external wireless adapter.

The Tube 2H operates in the 2.4 GHz band and integrates into existing wireless networks as an outdoor access point, bridge, or client adapter. When paired with high-gain directional antennas, it delivers superior long-range reception compared to standard-class devices, making it the preferred choice where signal distance is the critical design parameter.

Recommended for WISP operators, network integrators, and installers requiring a robust outdoor access point with maximum antenna configuration flexibility. Well suited for long-distance wireless links, outdoor campus coverage, industrial sites, and remote locations where wired infrastructure is unavailable.
