Sharing wireless internet access wirelessly

My sister lives in a small town in NH that started offering free wireless access in the center of town. I'd like for her to be able to connect to the internet from her house, which is about .5 miles away from the antenna but with tall buildings (church steeples) in between. She has a desktop, her husband has a Centrino-equipped laptop, and I visit with a 802.11-able laptop. My brother-and-law and I are thinking of building a cantenna or the like and mounting it on the roof . But what do we attach the antenna to? All the routers/"access points" I've looked at so far assume a cable (ethernet) connection as input signal which is then output as wireless or ethernet or both. But we want to both receive and dispense wireless. I know there are "repeaters" that can do this but all the affordable ones I've studied only output using proprietary protocols, not 802.11(g), which would require buying proprietary equipment for all the computers in question. Any inexpensive solutions?
