I have a friend who has a Rohn self-supporting antenna tower (like the one pictured) with a directional cellular antenna at the top. The tower is probably 40 feet high and was erected by a previous homeowner. They would like to make it useable again but the antenna needs to be turned to point at a specific cell tower.
The manufacturers documentation indicates that the tower is climbable but I've never dealt with these towers and thats outside my expertise. Who would I even call for that type of job?
I have one of these for 10m, vhf and uhf (ham operator). You can climb them if you don't mind heights, wear gloves and a roofers harness so you clip on. I put a rappelling rope on mine so I can just run the cleat up as I go.
