Telescopic mast (component)
A telescopic mast is a collapsible, free-standing, easily transportable tower, often consisting of a steel framework, with the help of which a temporary transmission tower can be built within a short time. Most telescopic masts are designed for the implementation of grounded antenna supports, but there are also designs with the help of which a self-radiating transmission mast isolated from ground can be implemented. The Bundeswehr, for example, owns the latter for its mobile radio station (“Radio Andernach”). Telescopic masts are erected after the catastrophic collapse of a transmission tower or mast, for measuring purposes in advance of the construction of a transmission system, especially for directional radio and sometimes also when reporting major events to set up a radio transmission link to the nearest directional radio station. Another use of telescopic masts is the construction of equipment for artistic demonstrations in the open air, in particular as an attachment point for a high wire .
