I haven't figured out how to post an image here, but here's a link to a photo of the CLE feed. It's using an Arrow ground plane antenna, cut for the air band. Two Bearcat 350 scanners and a Raspberry Pi computer. I'm a little less than a mile from the airport, so we're getting pretty good results.
Scroll down the page a little to see the photo.http://qrz.com/db/KD8RKJ
We added a feed for BKL on Friday Aug 15th 2014. It's using a 3 element yagi antenna at about 30 feet. I'm a lot farther from BKL, so the directional antenna is necessary.
