Tower Type help
Hello, I have identified most of the common classifications including Type A, B, G, H, J, K, L, M, guyed towers, and the various concrete/LSS designs. I have also seen references on Mark Foster’s old website mentioning additional tower types such as Type R and Type S that even he was unable to fully identify. What I am trying to figure out is whether there were additional tower types beyond the commonly documented ones, and how these unknown types were categorized internally by AT&T. There are also several towers that do not seem to clearly fit into any known type, but also do not appear to be “SP” (special) designs. Examples would include the Elliott, Illinois tower, Masonville, Kentucky, and Corbin, Kentucky towers. These structures appear to use repeatable designs that I have seen elsewhere, but I cannot match them to any documented type classification. If anyone has access to old ATT engineering documents, tower catalogs, construction drawings, microwave route plans, or personal knowledge regarding undocumented Long Lines tower types, I would greatly appreciate any information. I am especially interested in learning about rare or lesser-known classifications such as Type R, Type S, or any others that may not be publicly documented. My goal is to help preserve as much historical information about the Long Lines network as possible.
