Abstract
In this paper the theory, experiments and practical application of ball vibration absorber for horizontal movement are described, as well as its efficiency in comparison with that of the pendulum absorber. Two prototypes of such absorbers were recently realized on small TV towers in the Czech Republic and their dynamic behaviour started to be examinated.
