I had an attic antenna, and a house with aluminum siding. The attic antenna wasn't doing very well with WBBM-DT channel 3, but the UHF channels were coming in well. I read here that roofing materials can block quite a bit of low-frequency VHF signals, right where channel 3 is.
So finally this weekend I put the antenna on the roof, complete with a rotor. It's a big one from Radio Shack, with a 14-foot boom. I now get WBBM-DT steady at 65-70 signal strength, with no dropouts. The Masters this weekend was spectacular.
I would strongly recommend anyone who can't get WBBM-DT well to put something outside as high as possible, and with as long an element as possible. In the WBBM forum, Chuck DeCourt recommended a 92-inch element length, and mine must be pretty close to that.
