Research the situation. Current law requires the Telecom companies to rent pole space to cable companies. Keep in mind though, that you have to find a way of getting the cables up there, and then back down into the houses. You run the risk of frying things. Protect yourself with grounding devices.
Cable can only go so far.
UTP has a limit of 100m, or about 300 ft. It may be possible to get the cable to go farther, but you risk losing packets, and having a slow network to begin with. The better option is to consider other means of extending the network beyond that 300-ft per segment limit.
