Fred had two +12db omnis which were mounted on pipes. You need to mod netgear's AP not linksys to fit an external cable and antenna. The reflashed APs allow u to boost power to max (100mw). > The bad > thing about such an antenna is that it would be only directional. No. Only a directional antenna is directional in the horizontal plane. The omnis are directional in the vertical plane (pancake radiation - very little vertical radiation). The ones you are talking about are pringle's (tin can). They can give you massive distances of several kilometers. If u are very careful in the construction upto the horizon (40km). In a mesh you are interested in spreading, so omni it is. You can use a splitter and one omni and one directional to talk to another cluster. U can also use additional PA to pump the power. Fred has given me some PA chips. I will have them ready in 12 days for more fun. -- Rgds JTD -- http://mm.glug-bom.org/mailman/listinfo/linuxers
