Radio Masts and Towers
Radio masts rank among the tallest human-made structures, crucial for global communications
1 Feb 2026

What is the primary structural difference between guyed masts and self-supporting towers?
Guyed masts are made entirely of solid steel, whereas self-supporting towers are made of wood.
Self-supporting towers are always taller than guyed masts due to their design.
Guyed masts use tensioned cables anchored to the ground for stability, while self-supporting towers do not require such cables and rely on their own framework.
