 This is a most interesting thread. 

I am following it closely since I am using a full body harness for the first 
time and figuring it out along the way.

I am attempting to work on my 30 foot Rohn 25 Tower in order to 'stab my rotor' 
for my 3 element Hornet Tribander.

I have tried unsuccessfully three times (so far) to do so.

1) Rope not tied to antenna correctly (antenna wobbled around too much)
2) Gin Pole not long enough to stab antenna into the top section (mine has the  
tapered top) as I didn't account for length of the
center piece at the top)
3)  Attached a longer pole to the shorter one to make it longer but the wind 
picked up too much before I got finished and back up
the tower.

One thing I would like to say it that it is very difficult to estimate how many 
times I should wrap the large rope around the
opposite leg of the tower from where I am in order to sit into the harness for 
using both hands. Also when sitting into the harness
I can not figure out how to well manage the long pole while in the air.

In order to use both hands and stand on top to stab the short mast into the top 
is going to be a trick also. 

Is there a certain number of turns to make it hook back onto the harness hook 
on the other side while on the side of the tower and
how do you strap it to the top once you are ready to stab the mast into the top.
