I have been leaning towards a wireless bridge. There are not a lot of houses around, so the environment shouldn't be too noisy. My only concern is that I don't want to mount something external on that side of my house.
A good brand link with directional antennas will punch through quite a bit. I just mounted the wireless units inside at one end for my sister (although I did choose a mounting location that had thin wall).
Just need two dishes pointed at each other. That hard line is nice until it fails, which it will eventually.
