Radiolähetystornit

Radiolähetystornit, often referred to as broadcast towers, are tall structures designed to support antennas for broadcasting radio and television signals. These towers are crucial for the dissemination of information and entertainment over wide geographical areas. Their height is essential to overcome the curvature of the Earth and obstacles like hills or buildings, enabling signals to reach a larger audience.

The design of radiolähetystornit varies significantly depending on their purpose, height, and the type of antennas they support. Common types include guyed masts, which are supported by a network of cables, and self-supporting towers, which have a wider base and do not require external guy wires. Lattice towers, characterized by their open framework of steel, are a prevalent design due to their strength and relatively low wind resistance. Monopoles, a single, large tubular structure, are also used, particularly for shorter to medium heights or in areas where space is limited.

These towers can host a variety of antennas, including those for AM and FM radio, terrestrial television broadcasting, and sometimes even for mobile phone networks and other communication services. The placement of these towers is strategic, often situated on elevated terrain or in central locations to maximize coverage. Maintenance and structural integrity are paramount to ensure continuous operation and public safety.
