What is the ladder-like structure that runs up a tower vertically used to support the transmission cables?

Explanation:
It's the ladder rack, the ladder-like framework that runs up the mast to support and route transmission cables. This rigid structure provides a stepped surface where cables can be secured and organized as they rise along the tower, keeping them separated, protected from abrasion, and easy to access for installation or maintenance. A waveguide is a hollow tube for guiding microwave RF energy, not for supporting cables. A riser is a vertical conduit used inside buildings to carry cables between floors. A pulley is a device for moving lines, not a fixed support structure on a tower. So the ladder rack is the correct term.
