Here are a couple images of what the wireless radio looks like for the backhaul link. These images are courtesy of MonkeyBrains ISP in San Francisco but shows the same radio AU Wireless uses. The radio is just under 17" in diameter (medium pizza) and weighs 10 pounds. It does not require an antenna mast and can be attached to a pole as simple as an old satellite TV pole (the kind that holds a DirecTV dish to your house). The antenna itself that we use is smaller than a DirecTV dish.
