Interesting, since I was searching on the same today ;) I was planning on taking my WiFi adapter onto a parabolic dish for extending the coverage.

I read somewhere about cascading a series of (cheap) USB hubs for getting long distances. I'm not really sure how far that cud go. Any thoughts / experiences ??

  This is roughly half the cost of "traditional" extenders that used fibre optics to extend USB 2.0 over significant distances.

So, for anyone who'd really like the USRP right next to the antenna, something like this might be of use:


Now, I realize that the USRP2 will be using GigE, which will allow similar distances, but there are advantages to using the
