Transmission Towers

Transmission towers support the high-voltage conductors of overhead power lines, from the generating station switchyard right up to the source substations and satellite substations located near populated areas. Their shape, height and sturdiness (mechanical strength) depend on the stresses to which they are exposed.
To install transmission towers, workers typically build or improve a road to create access to the sites. Then workers prepare and pour concrete foundations, connect partially assembled towers and use cranes to complete the towers, which will be 900 feet to 1,500 feet apart.Structure sizes vary depending on voltage, topography, span length, and tower type.
For example, double-circuit 500-kV LSTs generally range from 150 to over 200 feet tall, and single-circuit 500-kV towers generally range from 80 to 200 feet tall.

Radio Towers

Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television.
Radio and television broadcast stations transmit their signals via RF electromagnetic waves.
The height of a radio transmission tower can vary greatly depending on its purpose and location. Some towers are as short as 50 feet, while others, like the KVLY-TV mast in North Dakota, the tallest structure in the western hemisphere, stand at 2,063 feet.
Radio towers are used for transmitting a range of communication services including radio and television. The tower will either act as an antenna itself or support one or more antennas on its structure, including microwave dishes. They are among the tallest human- made structures.

How do radio towers work?

Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves.
The radio waves travel through the air at the speed of light.
When the waves arrive at the receiver antenna, they make electrons vibrate inside it.

Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air.
They do not cause damage if absorbed by the human body, and they can be reflected and refracted to change their direction. These properties make them ideal for communications.

Telecom towers are essential structures that support antennas and other equipment for wireless communication. They are important for providing reliable and widespread wireless communication services.
Telecom towers are important parts of the connectivity and network coverage in urban and rural regions. Telecom companies use strategic positioning of these towers to ensure maximum coverage of geographic areas.

Telecommunications, also known as telecom, is the exchange of information over large distances. It's a broad term that includes various sectors, but all include a transmitter and a receiver. The medium of signal transference can be via various meansfibre, electromagnetic fields, light, cable, etc.
Whenever a cell phone is used, it emits an electromagnetic radio wave, called a radio frequency, that is received by the nearest cell tower's antenna. Once the cell tower receives this signal, it will transmit the signals to a switching centre.

Towers, masts, and poles are used to provide elevation, stabilized support, or position control for personnel or equipment. They provide a line of sight for viewing and illumination as well as the transmission and reception of signals.
In electrical grids, transmission towers carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations, from which electricity is delivered to end consumers; moreover, utility poles are used to support lower-voltage sub-transmission and distribution lines
Electricity towers are typically made of steel or concrete and can range in height from 20 feet to over 500 feet. Poles are usually made of wood, steel, or concrete and can vary in height as well. Both structures are reinforced with additional materials to withstand strong winds and other weather conditions.
According to Pole materials, there are 3 types: wooden utility poles, steel utility poles and concrete utility poles. According to applications, there are also 3 types: transmission poles, distribution poles and light poles.
