The point was using a lower loss cable for the long run up the tower, 
such as hardline, then flexible cable for the rotor/drip loop and short 
distance to the antenna feedpoint. At VHF, this is typical.

Failure is not necessarily the antenna. It could be the solid center 
conductor fracture after being flexed too many times :)

If you swap antennas and it's a single run of cable, you have to 
manipulate the antenna on the tower to access the feedpoint. Then, for 
example, if you put up a longer boom yagi, the feedpoint will most 
likely be further away from the tower and your existing feedline won't 
reach.
