I have a similar situation. The problem for me is that I have big stuff.
The antenna just above the top of the tower is a 6 el 20m beam that weighs well
over 200lbs (60 foot boom). Pulling an Orion rotor out of AB-105 is no small
task either. I had to climb the mast to fix a 15m beam that spun in the wind.
The pucker factor is way high and if you don't manage your lanyards right you
could wind up in deep shit real fast. Not good at 160 feet.
