A guyed radio mast. A guyed mast is a tall thin vertical structure that depends on guy lines (diagonal tensioned cables attached to the ground or a base) for stability. The mast itself has the compressive strength to support its own weight, but does not have the shear strength to stand unsupported or bear loads.
The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guy-wires. [1] A mast is a guyed mast, a thin structure without the shear strength to stand unsupported, that uses attached guy lines for stability ...
A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure. They are used commonly for ship masts, radio masts, wind turbines, utility poles, and tents. A thin vertical mast supported by guy wires is called a guyed mast.
Today, the most important aerial mast in Mühlacker is a 273 m high guyed steel tube mast with a diameter of 1.67 m, located at . This mast, which was built in 1950, is used as a transmitter for the mediumwave frequency 576 kHz and is therefore insulated against ground. It is designed as an antifading aerial and is therefore double-feedable and ...
A gin pole is a mast supported by one or more guy-wires that uses a pulley or block and tackle mounted on its upper end to lift loads. The lower end is braced or set in a shallow hole and positioned so the upper end lies above the object to be lifted. The pole (also known as a mast, boom, or spar) is secured with three

One mast was used and the other one was a spare unit. As aerials for shortwave transmissions of the Bavarian broadcasting company there are a dipole aerial, built in 1976, which hangs on two guyed steelframework masts with a height of 35 metres and a winkle dipole which hangs on three guyed steel framework masts with a height of 55 metres.
