If it's what I'm thinking it has very little UV resistance.
How tall is the tower? If the tower is in good shape and not terribly
tall I'd just install temporary guys of wire rope of sufficient strength
every 10' as I went up.
That's not the cheap way, nor the easy way, but it's the safe way.
OTOH if the tower is tall and has seen wind without a guy it is likely
stressed. Make certain the legs and reinforcement are all straight.
I'd be uncomfortable climbing something like that if every thing is not
right.
