The North Atlantic Treaty Organization (NATO) Troposcatter Station IDGZ was a telecommunications station located on top of Dosso dei Galli in the Brescia Alps. The station, which operated from 1969 to 1995, was part of the ACE High system, a radio communication network that connected NATO from North to South.

The IDGZ station was connected to the German Feldberg station to the north and the Italian Monte Giogo station to the south. The station used troposcatter technology, which allowed for line-of-sight communication even when the two stations are beyond the horizon. Troposcatter technology is reliable and works even in adverse weather conditions.

The IDGZ station was an important part of the ACE High system. The ACE High network enabled NATO to communicate quickly and securely during the Cold War. The station was closed in 1995, but its remains can still be visited in the late spring through late fall months (Apr-Nov) when SP345 is open over the mountain pass.
