Node consists of three access points - a routerboard 433ah with three wireless n interfaces - a ubiquiti routerstation with three wireless g cards, one 16db omni and two 15db yagi connected to a routerboard 433ah. I also have two linksys access points one running openwrt and one running tomato. These have 10db dual antennas. 20/4/2011 Put up omni antenna today - did a scan but unable to find anyone from melbourne wireless - will try some directional antennas tomorrow
