There was a huge dish pointing straight up. A friend and I walked around on the dish. There was a very small compartment more or less where the elevation axis was. The slightly creepy feeling I might get stuck in it kept me from going in but my friend did.
Another large structure was likely a transmitter. A large surface with a grid of smaller antennas covering one side.
Most cool to me though were the rooms with 6 foot high panels with all manner of analog meters, switches, lights.... Nothing worked of course, most everything was smashed. I wish now that I had brought some tools and removed as many of the components as I could.
My overall impression was a kind of wonderment that so much money and effort would be expended by the U.S. government to watch for Soviet aircraft/missiles. So much equipment built, foundations poured, cinder blocks stacked...
And then I suppose sophisticated satellites made it all obsolete.
