I lower the tower, block all sections independantly leaving some tension
in the cables and climb it. I feel as safe doing this as leaning a
latter up against it. Most extension ladders scare the hell out of me.
I fell confident in my abilities to block the tower and the
probabilities of mishap as certainly no more than droping antennas or
tower section into guy wires, etc...
For what it's worth...
