Abstract
The blast response of a 23 ft UHF Polemast Antenna was investigated in a free-field blast trial and in numerical simulation experiments. The antenna satisfactorily withstood the air blast loading at the nominal 7.0 psi peak overpressure location in Event Dice Throw, and the numerical model predictions for the natural frequencies and transient strain were in excellent agreement with the values obtained experimentally.
