Forum OpenACS Q&A: Response to Serving up OpenACS from home
It's the same connector that Lucent uses, I think.
I've been able to plug the buffalo antennae into both the buffalo base station and into some Orinico wireless PCMCIA cards that I had lying around. I've never seen a real Lucent antenna, though, so I don't know 100% that it uses the identical connector.
Hope it helps
