they may hold the weight
sure they hold you to get to the roof but hold you for 10 to 12 hours or so
now i know there are some that will get the job done
but just seems like the throw a peice of plywood on a y of a tree
I did see one that i thought would work laying out by a radio station
but it had a 4x4 platform would make a good two man tower
but i would have to drag it through the woods

The TV antennae in reference would be the self standing style with three of four poles connected every 12" or so with braces. I used to have one on the side of my house and would use it to get on the roof. They are quite strong and durable. After all, consider the force the wind exerts on the antennae during storms.
