Unless I'm totally screwed up I don't think this is right... everything below the geosynchronous orbit is orbiting too slowly to stay up on its own, everything above the geosynchronous orbit is orbiting too fast to not fly off unless anchored. So the maximum tension is where the cable crosses the geosynchronous orbit; there are minima at BOTH ends. In theory, you wouldn't need a lumped counterweight - you could simply extend the cable until the "loose end" had enough mass. This makes the presence of a minimum at the outside end more obvious!
