Outdoor WLAN USB Adapter

ALFA Network's Tube U(N) is a weather-protected WiFi USB Adapter for a connection to a PC/Mac or the ALFA R36 Extender Router. On the computer, this device replaces an internal wireless network card and provides excellent connectivity. The ability to position the device at an elevated location provides a good connection to remote wireless hotspots. The included software makes the detection and management of networks very easy and saves the preferred networks. All current security encryptions are supported, the security encryption can also be configured with the software. The use of this special software is not absolutely necessary under Windows, since the operation is also possible with Windows on board devices and the device drivers.

The ALFA Tube-U(N) is ideal for use on yachts, boats or campers as the weather-resistant, splash-proof housing is suitable for all environmental influences.

You can operate any Outdoor WiFi Antenna with a N-Female connector at the N-Male antenna port of the ALFA Tube-U(N).

The antenna is usually screwed directly onto the N-Type connector. At the lower end of the device is the USB 2.0 port, which is enclosed by a water-protected cable entry. At the edge of the housing are tabs for fastening the tube to masts or poles with the two included cable ties or with pipe clamps (not included).

If no mast is available,the ALFA Tube-U(N) can be made compatible with the standard marine mounting using the ALFA TSM1 Adapter. Thanks to the 1/4'' female thread of the Tube-U(G) it is possible to use suction- and magnetic mounts for action cams for fastening.

The ALFA Tube-U(N) supports the IEEE 802.11n radio network with 150Mbps in the 2.4GHz frequency range. The IEEE 802.11b/g/n standard is also compatible with the ALFA Tube-U(N) with a maximum of 150Mbps. Windows, Mac and Linux operating systems are compatible with the Tube-U(G) software. For operation with IOS and Android an ALFA Network R36 is necessary.
