    The tubular towers are easier than the lattice types - lay the tower over 
(after taking the antennas and mast off) and pull the sections apart to 
expose the cable connection; reverse the steps and you should be in business. 

    The messy part I was referring to is the motor drive although again it's 
easier than the lattice types. You have to get the tension and and limits 
correct. 

    I guess my question is why you think you need to replace the cables? If 
you have more than 6 broken strands, deep rust, or obvious damage then I would 
consider it. In the absence of those three conditions, I'd leave them alone.

    US Tower's insistence on replacing the cables every 3 years is a weasel 
clause (meaning they can weasel out of any liability if you don't follow their 
instructions) and is almost always unnecessary. This is not a violation of the 
LXC Prime Directive to "DO what the manufacturer says" because UST is NOT the 
manufacturer of the cable.
