There's still a "memorial" web site:

The Big Ear telescope "was larger than three football fields in size and equivalent in sensitivity to a circular dish 52.5 meters (175 feet) in diameter. The telescope consisted of a flat tiltable reflector measuring 340 feet long by 100 feet high (less when tilted), a fixed standing paraboloidal (curved) reflector which measured 360 feet long by 70 feet high, an aluminum-covered ground plane measuring 360 feet wide by 500 feet long, and two feed horns mounted on a movable assembly."
