Well guys, since this thread is going to become the definitive reference, I want to get a response on two other points.

First, since there are no repeaters, is this distance sensitive?. For example where I live, I have a T at my house because that's all I could get from a distance standpoint. Can this other circuit be ran to a cabin on the top of a mountian many miles from the CO?

Also, speaking of the high voltage issue. I have been told in the past that on a circuit such as this, it could be put in today and work fine. Then as the area around you built up, if you ended up with several of these in the same cable, your service got degradated. Is there any truth to that?
