Indeed, the others are broadcast antennas, perched on Lookout Mountain in Colorado. I was just curious about the one in the center, as you mentioned, as I'd never seen anything like it before. Thanks for the reply!Looks like there's several broadcast antennas there. The 8 bay in the center, which I believe you're asking about, is an FM broadcast antenna in radomes for weather protection. The others appear to be television broadcast antennas.
