The helicopter pivoted, the main rotor contacted a communications tower, and the helicopter then rotated 180° and rolled onto its left side.
The helicopter sustained substantial damage to the windscreen and main rotor mast.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.

Probable Cause: The pilot’s selection of unsuitable terrain for landing, which resulted in impact with brush and a loss of helicopter control.
