The Chicago Tribune has a brief piece today about the WDRV transmitter on top of the Aon Center. When the new antenna was installed on May 31, 2009 we Tweeted about it, and posted a picture of the installation. I'm re-posting the picture here for those who missed it.
For numbers junkies, the new antenna is 1,214 feet above ground level.
Some people don't like the new nubbin because it ruins the perceived flat top of the Aon Center. Those of us who can see Aon's roof have always known it was anything but flat. But I can understand why people may not like it. It's a pretty big change. The only thing that bothers me about it, though, is that it's not centered so it looks a little weird.
