They sell a bullet product as well as a couple other radios that take external antenna. They also sell a large selection of antenna.
If you (or anybody reading this thread) get a Bullet, do NOT get the 5 GHz Bullet if you live in the U.S. Ubiquiti screwed up their DFS implementation. Rather than blocking out just the DFS frequencies, they blocked out everything below channel 149. As a result, the 5 GHz Bullet cannot connect to hotspots using the non-DFS channels 36-48.
I was in contact with their tech support for several months trying to get this resolved, and they never did. As a result, I have a shiny 5 GHz Bullet Ti sitting in a box since it's unable to reliably connect to hotspots which auto-change channels (sometimes they change to channels 36-48). It's a fine piece of hardware, much better at pulling in a signal that other devices using the same antenna cannot. But it's hopelessly crippled by this software error.
