Gemelli was established in 1947 and its original name was "Laboratorio Radio Gemelli". Its main goals were the design and the production of radio equipment for aeronautical and marine applications. This equipment operated on the VHF band. At the time the names of products were Shark, Narval and Swordfish. They proved their reliability and good performances for over twenty years operation and some of them were even used by the Italian Team who first reached the K2 summit.
