"Misplaced" is probably an understatement.
The Aerial was 21M high and extended from the top of an ILS Calibration van which had been authorised by the tower to enter the runway just prior to the aircraft arrival. The crew thought they had been struck by a bird.
Damage was to one tyre, which was only observed after aircraft was shutdown on stand.
Currently subject of an ENAC ( Italian CAA) investigation.
