RadioLabs Wave Magnum

Overview
The drivers provided by RadioLabs indicate this device is using an RTL8187(L/B) chipset.

An eBay listing here (archived @ archive.is) indicates that the top portion is aluminum, the bottom portion is acrylic (or some translucent plastic), and the wireless module used is indeed from an AWUS036H.
 * This Amazon review indicates that the device is simply a repackaged ALFA Network AWUS036H (w/ a custom made Aluminum / partial Aluminum shell).
 * The reviewer also states the USB WiFi Repeater sold by RadioLabs is also an ALFA Network R36.
