When I first moved into my new apartment one of the first things I noticed was an old Primestar dish sitting on the roof next to the porch. Primestar was bought out by DirectTV in 1999 and unfortunately no longer supports Primestar dishes (so it won't be possible to share my dad's DirectTV service) but I found a page that describes how to convert the dish into an 802.11b antenna. Although not terribly useful, if it can strengthen our wireless signal for the porch and our attic it might be cool. We'll see if I have the energy to try it out sometime...
