Camouflaged or concealed towers are meant to blend in with their surroundings. (Some people also call them stealth towers but Stealth is a trademarked term so the proper term is camouflaged or concealed.) It's often the case that municipal zoning codes require that concealed towers be built in certain areas, if not all areas of the city. They can be designed to look like trees or even church steeples. The trees are put together much like artificial Christmas trees. You build the trunk then bolt on the branches. Because these concealed towers are supposed to look real, there are no climbing facilities on them. No step bolts and no ladders. In order to climb into the branches, tower owners have to bring in a crane and hang ropes in the tree at the beginning of the job. Once the ropes are in place they climb the ropes to their workstations, which are sometimes as high as 120''. At the end of the day, they descend on the ropes as well. Concealed design makes it more complicated and more expensive to work on the structures and can double the amount of labor time it takes to do a simple antenna swap.
