The Stanford University Dish some 46m or 150′ in diameter was erected in 1961 and became one of world’s largest dish antennas, even today. The Dish was commissioned by the Stanford Research Institute that later became SRI International. This fact made complete sense when one was standing at the control position and proudly posted on the console was the amateur radio call-sign of W6SRI. The dish is primarily used to support spacecraft operation as it is located in an electrically noisy area limiting radio astronomy work.
