wireless bridge

Is it possible for a router in bridge mode to broadcast wirelessly? I want to add wireless internet to a house 200 feet away. I have an omni directional antenna on my roof (connected to a d-link dir 655) and a direct line of sight. I have another omni directional antenna and two linksys routers flashed with tomato. As I understand it I can set the linksys router to bridged but then I have to hard wire to connect to the internet. Is there anyway to make the bridged router broadcast a wireless signal. Could I use what I have to set up some sort of a base/repeater? Thanks
