This is what it is all about. Behind the sandbags is a M-1945 Shelter and inside it are two radar scopes (UPA-35). The scopes display the information gathered by the big antennas and the men of Team 3 pass this information to customers all over the skies. The radios they use are AM, FM, Microwave, Longwave, Shortwave and two tincans with a piece of string. They all require their own strange antennas
