Hello All,

I have been asked to help take down a tower for a friend, Scott, AG4GO. It 
is 10 sections of Rohn 25G in commercial use that was given to my friend for 
free. The top section is a sleeve-top, and there is a single, 
folded-monopole commercial antenna on top.
After inspecting the tower, I determined that it definitely was not properly 
installed. It is only guyed at 2 heights, 50 and 90 feet, and the anchors 
are 12 foot, 4" diameter steel pipes that make inspecting the guying 
hardware difficult, since they are so high. There are only 2 cable clamps at 
each termination, and some of them are saddled on the wrong side, pinching 
the 'live', load-bearing side of the cable.
Some of the hardware has a little rust, and the top guys are loose with 
considerable sag.
All of the tower joint bolts are rusted and some of the joints we could see 
at the bottom had been overtightened such that the legs were somewhat 
squeezed out-of-round. However, the sections themselves seem to be 
structurally sound.

This tower has been up for well over 10 years. The guy hardware is 
substandard, but not broken. I think I could climb the tower safely if I 
placed temporary guys on it, but I am hesitant to do this.

Scott can arrange for a crane to help us, very inexpensively. My question 
is, can this tower be picked up and layed down in one piece without bending 
it? This would be much safer, and would allow many people to work on the 
tower joint bolts simultaneously, saving us a lot of time.

If any of you have done this with Rohn 25 of similar height, please write 
and describe how you did it.

Any other comments and recommendations are welcome.
