The dome on top of the main building covered our search radar antenna. The dome on a tower just next to the main building covered the antenna for the height finder (radar). After arriving on site, I was shown to my room inside the main structure, which we called the "composite" building. I grew to know that room and the rest of those surroundings quite well, and to especially enjoy the men stationed there. I both lived and worked inside the main building for the eleven months of my tour.
