[Mesh] connecting to Laney College 5ghz node

hey all, I'd like to implement a connection to the 5ghz node sitting on top of the 7-story building at Laney College. We've got some 5ghz antennas: http://www.l-com.com/wireless-antenna-49-58-ghz-27-dbi-lightweight-die-cast… I believe we do have some 5ghz Ubiquiti Nanostations, but as far as I'm aware we would have to hack them to work with the directional antennas we have around. Sub-ideal. Looking for a cheap alternative, I'm thinking about buying one or two of these Ubiquiti Bullet5 routers: http://www.ebay.com/itm/UbiQuiti-Bullet5-5GHz-802-11a-100mW-outdoor-wireles… Does anyone recommend an alternative device? Also, let me know if you want to participate! // Matt
