There is a range of paraphernalia relating to towers, in particular items dealing with RF issues and other equipment mounted to telecommunication towers.
Equipment like, lighting protection systems, special footings, guy wires, brackets and other mounting hardware, tower camouflage/disguises, aircraft warning features, etc..
Masts and towers are located in just about every location on Earth. From remote deserts to heavily developed CBDs, they experience every known condition - extreme cold and heat, salt spray, high altitudes, destructive winds and lighting strikes, and seismic activity like earthquakes.
So it's no surprise that their attachments must suit the same conditions as the towers themselves, and designers are faced with a myriad of challenges to ensure the best performance of RF equipment, from simple mounting clamps and outdoor boxes to RF shields.
