The plan had better be basically for self-rescue. It's been awhile, but I
believe the time limit for starting rescue is three minutes. This is where
SRLs would be a good idea.

That's called a Self Retracting Lifeline.
You could actually install one at the top of your tower below the guy
points, attach a line to the hook, then pull it down when you need to
climb. In this situation, you would never want to leave your lifeline
exposed to the elements the entire time, hence the attached line to
retrieve it.
Granted, these aren't cheap, but I guarantee they're less expensive than a
week in the hospital or your funeral.
However, you can get an 11' web SRL for $376 if you're going to do the
"movable" plan.

The only climbing company that also makes OSHA approved harnesses is Yates.
It's a liability and hassle thing.

The climbing belt is strong; the real weakness is in your pelvis. Guess
which one will break first!
Climbing belts never worked for fall arrest situations. Physics is a
constant; our understanding of the physics and human physiology evolves.
